It's actually a 6s stun. iirc it "should've" been used for A3s or A8s for stunning the slimes and orbs during add phases. Tho, double WAR or DRK/WAR was the standard during that time, soo... pretty invalid.

With all the removed actions since SB and ShB, I am amazed how this skill even survived its cut. It was still useless in SB due to its high 120 TP cost, and stun resistance is still a thing. They also removed blinding effects (Flash, Dark Passanger). So yes, this skill IS out of place.
