The Alien Spore Thrasher is a parasitic organism that propagates with special spores that drift around looking for a suitable, moist, living environment to start growing in. A tiny intermediary form is assumed by the thrasher, barely anything more than several sacks that produce a mixture of venomous secretions and a set of mouthlike tubes that connect to the host organism. The spore thrasher kills its host in short order and consumes its body to grow the thrashing fruiting body depicted above. The stats below are for the fruiting bodies of large spore thrashers that grow in the metal arm forest ecosystem from the body of fallen metal arm trees.
HP: 1d4 x 100 HP
AC:20 FORT:22 REF:25 WILL:18
Basic Attack: melee reach 1 Thrash +12 vs. REF, 5d12 dmg
Minor Recharge 4,5,6: Release Poison Spore Cloud Close Burst 1d6(6's explode on the radius of the burst roll- roll an extra 1d6, all subsequent 6's also explode) (choose 1 spore type)
Redirecting Cloud : Until the end of the Alien Spore Thrasher's next turn, if any enemy rolls a natural 1-4 on a melee attack roll, the thrasher chooses a new target for the attack and the enemy must reroll against the new target.
Stupifying Cloud: Persists for 1d6 rounds. Any creature beginning its turn in the cloud or entering the cloud must immediately make a save or become dazed, save ends.
Blinding Cloud: Persists for 1d8 rounds. Any creature beginning its turn in the cloud or entering the cloud must immediately make a save or become blinded, save ends at -2.
Infecting Spores: +20 vs. FORT vs. all in burst. Those hit are infected. The tiny growing organism rolls Stealth +30 to hide its presence (and avoid future heal checks). 1d4 days incubation period. -3d12 HP from Max HP total. Save at -2 each extended rest or the infection progresses, -1d12 additional HP from Max HP total. Three consecutive saves ends the infection, as does magical healing specifically targeted at the infecting organism.
