FFXI didn't seperate damage per hit for multi hit weapon skills and instead totaled it all for a final amount. This caused these type of weaponskills to vary greatly in damage range when used with things like the passive double attack and triple attack traits which could proc on each hit of the weaponskill and weapon passive effects that could multiply damage. And as I found out as a DRK using an apocalypse to close a LV3 skill chain. When all passives and extra effects line up and everything procs... you break the game's enmity system if the thing you hit survived.
