Will-o-the-wisp

Useful Info

Will-o-the-wisps are intangible puffs of flames found primarily in the Swamp. Their Marshlight spell behaves exactly like Foxfire - it creates 2 foxfires, which quickly rush towards you, dealing damage on contact.

Tips & Tricks

• Having fire resistance is recommended, due Marshlight's high damage output.
• Wisps have many resistances themselves, so elemental spells are less effective. If you rely on elemental spells, you can use bolt wands (wisps don't resist acid), a tin of tremorstones, or irresistible spells like Airstrike to take them out.
• Foxfires require an open path in order to hit you, so you can potentially use corridors and monsters to block it. Unfortunately, it's hard to take advantage of this quirk in the Swamp, which is very open.
