Sporesweeper

Two delves qualify for this achievement: Fungal Folly in Isle of Dorn and Mycomancer Cavern in Hallowfall. Mycomancer Cavern is recommended because the Mushroom Morsei story variant has you defeat the boss at the very beginning of the delve, leaving only add clears for the remainder.

Touching a spore and activating it does not fail the achievement — only being hit by the explosion after activation does. If you accidentally activate a spore, move away immediately before it detonates.

Fight enemies carefully and avoid pulling groups near clusters of spores, as combat movement near spores increases the risk of triggering explosions. You can intentionally kite activated spores into nearby enemies to use the explosion as a damage tool.

If running the Scavenger Hunt variant, the boss alternates between two islands. When the boss begins casting Sporesong, move to the opposite island to avoid the incoming spore explosions, then return and continue the fight.

This achievement tracks individually per player — in a party of five, some members can earn it while others do not, so being hit does not affect your groupmates' progress.

If you play a pet class, your pet being hit by Explosive Spores does not count against you and will not prevent the achievement from completing.
