Illuminant Slime

The Illuminant Slime is a monster that appears only in the Underground Hallow after defeating the Wall of Flesh in the world.

The Slime looks similar to other monsters from the slime family, it is pink-purple and emits some light. Upon moving, it leaves a small trail of pink similar to the effects of the Ninja vanity outfit.

It has quite a bit of health points and can deal up to 50 damage, so is quite dangerous for an unprepared player, especially when joined by other Underground Hallow mobs.
