The following table describes the level scaling. Note that values may change in Co-Op, some Quests, and certain Domains (such as the Spiral Abyss). The change usually involves multiplying some of the values by a constant scale factor.
Behavior and Attacks
Upon entering combat, they will be in their ignited state (they will be affected by Pyro) and will be aggressive, exhibiting normal small slime behavior:
They will first distance themselves from their target. After reaching the "safe distance" they will move closer to hit their target by jumping at it, dealing Pyro damage and inflicting it with Pyro. After successfully completing the attack, they will retreat again.
If defeated in this state it will explode after a short delay, dealing AoE Pyro damage.
If Hydro or Cryo is applied to them, they may be extinguished. In this state, they deal Physical DMG when attacking and other elements can be applied to them. They are still immune to Pyro damage when extinguished. When defeated in the extinguished state, they do not explode.
2 Cryo attacks or 1 Hydro attack can extinguish a Pyro Slime. When ignited, Electro, Anemo, and Geo attacks may extinguish them for a short moment, but they reignite automatically afterwards.
When extinguished, a Pyro Slime may attempt to move away from its target to reignite, if given an opportunity during combat or after the battle ends.
