/facepalm D:
First of all its not a SQI ingredient, it was a skill added to Sherwood time ago.
Probably Violent Gale was the most useless skill EVER on a SQI, okay guys, how many of you used Violent Gale when you played Stalker (like, as part of your normal killfest)?
Violent Gale gives a + flee bonus when you're wearing a Wind enchanted armor by the way if you're under the AoE. It proves useful for flee builds, but since its very uncomfty to have to be always casting that thing while you move around the map...
Imo, Violent Gale was disabled because no one ever used it, and to put Critical Wounds instead, wich proves more usefulness in WoE / PvP aspect, wich is what SQIs are supposed to be aimed for.
The description is still on the SQI because maybe GMs forgot, it's not like it takes a long time to remove anyways.
Last question is up to you.
