Using the Quasit in Combat
In combat, the quasit excels at drawing attacks away from fragile spellcasters and harassing enemy backlines. Its fly speed gives it excellent positioning, letting it threaten archers and control key zones.
Use the quasit to deliver poison spray to weaken groups before your main forces engage. Pair it with spells like detect magic to track enemy preparations and reveal stealthy threats in your arena.
