993 is still a lot of damage. Were you taking into account the resistance the player had, and their lightning res? Those can reduce the damage significantly. If not, then it's likely this is the normal amount of damage you're seeing, and not a bug. That amount of damage is nothing to complain about, either, so I wouldn't even say a buff is needed. That's a OHKO in a lot of cases, if you can land it.
