Recall Knowledge DC 18 (arcana)
Disable DC 16 nature (trained) or DC 16 occultism (trained) to repair the runes, DC 20 survival (trained) to disturb the soil within the ring to weaken the mushrooms; one successful check to disable this hazard reduces the mushrooms' hardness to 0, and two total successes are required to disable the hazard.

Giant mushrooms sprout from the ground, their caps reaching up to 15 feet high. Each giant mushroom flls up one 5-foot square and can appear anywhere within 20 feet of the center of the ring except adjacent to another giant mushroom. The ring can be disabled but not damaged before it activates.
