Igeki is the first of a three-part combination used as a sure-kill technique.

The user makes a single melee attack with his held weapon. If it hits, it deals an additional 10 points of damage and forces the target to make a Str save to avoid being stunned for 1 round. The additional damage is not multiplied on a critical hit.
