Item: Necrotic Cap (Greater)

Activate Cast a Spell (add 1 action)

---

You can use this slimy, rotting mushroom as a spell catalyst when you cast an Acid Grip spell by tapping it against the target, causing the mushroom to release a cloud of necrotic spores. When you do, acid grip loses the acid trait, gains the fungus trait, and all acid damage the spell deals becomes void damage. On a hit, the target additionally gains the Enfeebled 3 and Sickened 3 conditions as the spores consume their flesh. As long as the target is taking persistent void damage, they can't reduce the value of their sickened condition below 1.
