There's only type of whipping cane and one type of combat staff. The whipping cane is from Abbot Roo's store, Miss Devious' shop, and crafting.
All the "weapons" with high incapacitation chance:
- Whipping Cane - 100% (89% + 11%)
- Combat Staff - 81% (70% + 11%)
- Ice Dragon, a unique 30 base damage armor piercing weapon for Clea Vallas that cannot be unequipped - 81% (70% + 11%)
- The Incantation [Voice of Adem] which takes away 125 HP and costs the player 3 Willpower (1 Willpower at the highest occult level) to cast - 100%
Incantations can be learned from books gained during the Prowler in the Depths questline part 3.
