Fix Vargh Redemption AI
When playing as an alchemist and wielding Vargh Redemption, the ring's Tidal Wave talent would automatically trigger if you switched to your golem. This happened to me in Angolwen and hit one of the mages. Fun ensued.
Compared to the normal Tidal Wave talent, Vargh Redemption's copy didn't have the requires_target
field set, which resulted in the tactical AI deciding it was fine to fire it. I added the field, defining the target and radius similarly to Tidal Wave.
