Scarlet Rot is a Status Effect in Elden Ring. Status Effects are various buffs or ailments that apply either a beneficial or detrimental effect to the target. Status Effects can be applied on both enemies and players alike. Status Effects are triggered after a buildup meter is filled by repeated application of attacks that cause the effect. Both players and enemies can have varying resistances to a given Status Effect.

 

Scarlet Rot Information

Scarlet Rot does damage over time based on the target's health. Damage does not scale with weapon. The effect deals damage at a faster rate than poison, but has an overall shorter duration.
Immunity will slow the buildup of the effect on players, but will not affect the damage taken from the proc.

      There's 1 more scarlet rot type not mentioned here.

      If you roll in lake of rot and leave you'll be dirty and still build up scarlet rot. If you don't use soap to clean it, you get a weaker version.

      It still outdamages regen equipment+regen tear, but not as fast as the normal one from lake of rot.

        So a solid strat for dealing with low level hosts is to get a good supply of rot items I use both pots and arrows then make a back up that you can load to essentially get an unlimited supply once you run out load the back up it works best in early dungeons because the game doesn't give much that early so the only way the hosts can get a cure is by their gank squads using something like ce to drop boluses for them if you can get rot to proc you're free to run off and use the mimic veil to let the rot do its thing find a good hiding spot and even if they cure it they will have to live in paranoia until you decide to leave

          I remember as a spear & shield user, the only way i can solo that WWE smackdown boss is by using this... Never know that rot can work on some bosses, lol.

              So sick of these low level twinks griefing my co op sessions man. So cool that you downloaded a cheat save with all the rot pots. You're dead but congrats you successfully rotted the host so now the session is over. That's just griefing lol.

                Been playing Elden Ring since launch with several different builds and decided I was going to try a rot build for fun on a final playthrough until DLC. Well I thought I knew the game well until I found out there are several different strengths of SR. I am so damn confused. Like when I saw Rotten Crystal Swords say "slight" buildup, I assumed it meant the build up was slow, not that it was a whole different category of damage scaling. I know there are two different types of poison, normal and deadly, but am I to understand that there are MORE THAN TWO different types of SR that players can inflict? I'm not that smart, so if anyone could explain slightly clearer than the wiki, well I think that would be cool.

                  For completeness's sake, assuming the given numbers are correct, both rot swamps do enough percent damage to kill you 3.6x over, plus 1440 for the Aeonia swamp (around 1 health bar with 40 vigor), and plus 5400 for the Lake of Rot (around 2 health bars at 60 vigor with Morgott's Rune). Not that the duration of the status matters a ton when the buildup is persistent.

                    Anyone else really wish there was contact medicine for the rot swamps? Come on Miyazaki, you already know how to do this.

                        Where rot infusion and rotten armament spell? Why is weapon rot so useless? Where are the cool rot spells like the ones that frenzy, ice, and bleed got? and the last, most important question… WHY DOESNT HAND OF MALENIA INFLICT ROT!!!!!

                          should scale off faith and all rot weapons get tiny faith scaling.
                          then you could put poison on one and us fai arc build who use stinky stuff can finally get some damn numbers.

                            I just poked him with the Antspur Rapier, to apply Scarlet Rot once it was on I just kept my distance. It took 3 applications of the rot but it put him down.

                              Because of game logic, nearly every enemy in this game can be afflicted with Rot that isn't a statue, already a Rot creature, or God itself. Because of that, it's not a bad idea to start every fight ever with a rot inflictor. Rot bone bolts from the Pulley crossbow, Rot pots, and Ezykes Decay if you're a faith build are all good options. Don't sleep on this status just because it doesn't have that many options to inflict it.

                                It kinda sucks that two of the weapons that inflict Rot are unique, and the rest are just "another weapon dipped in rot". Wish we had more unique rot weapons.

                                  I don't know if I'm crazy, but it almost seems that attacking an enemy afflicted with rot with a weapon or spell that can also inflict rot, it does increased damage. Is this real, or I am just stupid? I'm thinking I'm just stupid.

                                    Malenia herself is not immune to Rot but some random assassin who is literally as far away from any rot exposure as possible is immune. C'mon guys.

                                        To all those that wish this was better, just remember that this is already poison but better. The only advantage poison has is being slightly easier to proc

                                          Does this stack with Poison? It seems whenever I proc Scarlet Rot they lose the poison bubble and it only does regular Scarlet damage

                                            AKA the passivity destroyer. even better in conjunction with poison. if you gonna play like a b****, you're gonna die like one

                                                I really like scarlet rot but I wish melee builds with it were more viable for playthrough. There are very few weapons that inflict scarlet rot, most of them are in late-game locations, and there are zero ashes of war that inflict it

                                                        Something to be noted is that holding the Cleanrot Knight Spear gives you bonus immunity (50), which makes you more resistant to Scarlet Rot ofc

                                                          The effect will build up over time when standing in pools of scarlet rot, but I've noticed that levels will continue to climb once you exit the pools, but only if you roll in it.

                                                            The rot flowers the scarlet rot creates, especially during boss fights with characters fighting with scarlet rot (Malenia) look similar to a real-world plant disease called cedar-apple rust, it also produces orange colored flower-like structures on infected cedars.

                                                              Not really. If you invest heavily in it it'll cause it to build up over 4 seconds instead of 3 seconds. It's mostly just to make you feel better.

                                                                                  - Caused by Spells, Rotten Stray Ashes, Rot Pot
                                                                                  Only one weapon had inflicts weak scarlet rot written as passive effect but they do all the same so thats what i called it.
                                                                                  The normal scarlet rot scales a lot better so it may be better to use rot pots instead of rot weapons for non casters.

                                                                                    There's actually a scarlet rot source even more potent than the lake of rot: a 3.3%+26 per tick that lasts for 180 seconds. However I am not sure what exactly is this source.

                                                                                    My guess is malenia's virus bomb, if the initial explosion somehow didn't kill you.

                                                                                    • Anonymous

                                                                                      I love scarlet rot for the lore implications. It would be nice to have more viable builds around applying it in PvP bc rn it's just underwhelming

                                                                                      • Anonymous

                                                                                        So, to be clear- the ultimate goal of using SR is to "fill" the target's "SR bar"- thereby applying 90 seconds of the DoT? And the damage is purely a function of the target's health pool? So bringing multiple sources of 'Rot to a fight is not then beneficial then (using the dragon incantaion, having the Rotten Stray, grease, etc)?

                                                                                        • Anonymous

                                                                                          • Anonymous

                                                                                              May i know does the scarlet rot stack with FROSTBITE effect, please?

Add Swarm Pot or Swarm of Flies, and you almost never have to swing a sword once.

                                                                                                Damage-over-time play in this game almost makes me miss my Affliction Warlock in WoW. DoT and forget.

Wearing the full Mushroom set, with Immunizing Horn Charm and Mottled Necklace+1, the buildup was just as fast as it was while wearing the Bull-Goat set without the charms.

                                                                                                  • Anonymous

                                                                                                    It's just a bit stronger than poison, and I still gotta sit there and wait for it to do actual decent damage to bosses. Unless they nerfed it recently, for me it's about as useless for bosses as poison is.

Kills you way slower, but it seems like it has a mind control aspect to it, like Cordyceps, that forces its hosts to try and spread it.

                                                                                                        • Anonymous

                                                                                                          Utilizing slight approximations, a bit of guessing, questionable math skills and the limited data below, I came to these results:

                                                                                                          Strong rot (Lake of Rot) = 30 + 2% max health for 180 seconds
                                                                                                          Medium rot (Aeonia Swamp, Malenia (?), some other bad places) = 16 + 1,5% max health for 180 seconds
                                                                                                          Weak rot (generic enemies) = 15 + 0,18% max health for 180 seconds (data stolen from the guy below, but also tested beforehand)

                                                                                                          These are the values on PLAYERS not on enemies, I have no clue about them, but they might follow the same formula with reduced duration, if a boss has 10000, then the weak rot would deal over the course of 90 seconds 1350 + 16,2% = 2970 which sounds strong but still reasonable as a value.

                                                                                                          Now, if someone could test further and confirm so we can add this on the page it would be delightful.

                                                                                                          • Anonymous

                                                                                                            The formula for a full cycle of Scarlet Rot is (15 + ((Max HP * 18) / 100)) * 90.
                                                                                                            Which means it deals 0,18% Max HP + 15 flat per second and last 90 seconds.
                                                                                                            If somebody wants to edit the info above.

                                                                                                              First of all, I found out that in the Lake of Rot the buildup version from rolling in the liquid rot and the rot received directly from walking on the liquid are different. The buildup version is much weaker and is more "convenient" to have while walking around. To do it, simply roll in the liquid, get back to the ground and let the bar fill up, then walk around as you want with the weaker version as you are immune to the stronger version.

                                                                                                              Second, Scarlet Rot seems to deal flat + % max health damage and it varies depending on the situation. Values are tested in Lake of Rot:
                                                                                                              1450 HP (naked 40 vigor) receives 59 damage (4,07% of max health) per second and 37 damage (2,55% of max health) from the weaker version
                                                                                                              1508 HP (40 vigor, erdtree favour+2) receives 60 damage (3,98% of max health) per second and 38 damage (2,52% of max health) from the weaker version
                                                                                                              1644 HP (40 vigor, erdtree favour+2, radagon soreseal) receives 62 damage (3,77% of max health) per second and 40 damage (2,43% of max health) from the weaker version
                                                                                                              1775 HP (40 vigor, erdtree favour+2, radagon soreseal, crimson amber medallion+2) receives 65 damage (3,66% of max health) per second and 42 (2,37% of max health) from the weaker version

                                                                                                              From this we can see that getting more HP helps with not being vulnerable and low health, as the rot hits for decreasing portions of your health as your health goes up, while having low HP helps in terms of overall survivability because flasks heal a flat amount, as such receiving a lower damage means your overall healthbar lasts longer, however I'm not sure how convenient it is to get chunked for 4% or more every second.

                                                                                                              • Anonymous

                                                                                                                Tested on Elder Greyroll using Antspur rapier. ARC of 12 if that matters?
                                                                                                                Did 15,000 damage over those 90 seconds, which is interesting. because it suggests some %hp scaling. But it must also do some flat damage, because it fully kills enemies with less/normal hp. so it cant simply be doing like 20% their max health. so, some flat and some % hp scaling? Maybe elder greyroll is just an exception?

                                                                                                                • Anonymous

For NPCs and Bosses it seems to total 35-40% of their health pool but for players it does like 400% of their total health lol. It might be like Dark Souls 3 where different sources of scarlet do different damage % but idk.
