We’re gonna need you to bring a bit more details to the table in order to figure this out.
Anyway, if I get it well, your ki attacks do only 1 damage.
Custom or not ?
What’s your WIL ?
Was it a direct hit or AOE damage ?
What are the concerned mobs exactly ?
Are you using only DBC ? Plugins ? Mods that could affect vanilla mobs only ?
See, we need clues.
