Base Serpent Messmer steps up once you've depleted Messmer the Impaler's health to 50%. His health remains at 50%, which gives you and advantage. In this new phase, Base Serpent Messmer not only retains his old form's original attacks but also introduces a set of new, more lethal attacks that's done by his red snake. The battle begins with the Serpent Fireball which is where he turns into a big serpent and hurls a massive fireball, then reverts back to the humanoid form. In his humanoid state, he executes his attacks with increased speed compared to his previous form, making him a more poerful boss.

Among the fresh additions to his moveset is a snake transformation that does a bite combo followed by a powerful ground slam. However, one of his most powerful attacks is the Fire Grab. This technique has his right hand engulfed in flames. He'll unleash a torrent of fire from his grasp while impaling his spear to you with flames, almost guaranteeing instant death.

Proceeding in this battle requires a slow apprach to Base Serpent Messmer's abilities and vulnerabilities. Capitalize on the small opening right after he uses Serpent Fireball to unleash a ton of heavy strikes, increasing your damage output. When engaging his humanoid form, maintain an aggressive approach but be ready to switch to defensive the moment he transforms into his serpent form. His serpent attacks pack a punch, requiring you to dodge and counter.

Above all, remain alert when you notice Base Serpent Messmer's right hand glowing with flames it's a sign of his powerful Fire Grab. React by backing away and rolling back, giving you high chance to evade this lethal attack.
