Major Necrotic Cap

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 and sickened conditions, with the listed values, 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.
