Spore Burst (poison)
Frequency three times per day
Trigger A Small or larger creature touches or attempts to enter one of the three tents

Effect The thorny vines of the three withermolds growing on the tents suddenly whip into a frenzy, filling the air with clouds of toxic spores. All creatures within a tent or within 10 feet of a tent's exterior take 8d6 poison damage (DC 32 basic Fortitude save). The withermolds then roll initiative.
Melee Thorny Vine +26 (reach 20), Damage 1d10+5 piercing
Routine (3 actions) A withermold makes three Strikes with its thorny vines on its turn, splitting its Strikes up among potential targets before striking a single target more than once.
Reset A withermold deactivates at the end of any round when there are no targets within reach to attack with thorny vine Strikes. It resets immediately unless it's used all its Spore Burst reactions for the day, in which case the withermold resets in 24 hours.
