The druidic spell is a spell scroll that can cast Bloom on rotten logs in Mort Myre Swamp to grow Mort myre fungi.
The spell is given to the player by Filliman Tarlock during the Nature Spirit quest and can be used only once, after which it turns into a used spell. However, after completing the quest, the player can cast Bloom using a Silver sickle(b). For collectors, be cautious about dropping this item inside the grotto right before the quest's end. If left on the ground, it will disappear when the grotto shifts.
