Mortal Shell 2 Tarstones

Tarstones modify weapon behavior, damage, finishers, status effects, or utility; choose them around a weapon’s actual moveset rather than rarity alone. ^[wiki]

Balance Patch 1 buffed Parasitic, Grudge, Bulwark, Clerik’s, and Squall stones. Re-test any launch build that ranked those stones poorly. ^[patch]
