Inflicts absolutely no damage, but does inflicts Bleed, Poison, Toxin, Estus Cork, Vow of Silence, and on a Backstab or Riposte also inflicts TWoP in addition to all of the above. Takes all four weapon slots to use. The duration of Estus Cork, Vow of Silence, and TWoP are shorter than inflicting them through other means. Reinforce to increase length, the weapon has respectable properties when defending.
So... I can hit someone once and give them all these statuses... and then switch out to anything I want basically. Or are you binding it, in which case the only way you can kill things is from poison, toxic and bleed of which many bosses are immune?
Fist of Knockback. 0 damage, special great fist weapon type - attacks similar to mushroom's windup punch but without tracking, no lock-on, 10 durability, 30 weight, takes two slots, ignores block and poise, upon hitting the target knockbacks it at the large distance (similar to BKGS 2HR2). Can't backstab, upon parrying the knockback distance doubles. If the target flies into wall or other enemies does heavy damage to everyone affected, proportionally to the shortage of distance.
