^This, also get enough points in stampede to remove cooldown(6 or 8, don't remember) for general clearing and you're all set. Rebound and overkill are bad with Snake stance. Stampede/snake bite is the way to go.
Does anyone know how Purify works? I finally got that stupid ring from Duncraig but the Purify skill does not deal damage to Assur! It is really frustrating to go through all that trouble just to get a ring that does not even work. Also his charm really seems like it is pretty useless which almost makes it seem pointless to even try to kill him. The end game is just confusing me at this point. Why even have an endgame if there are no actual rewards and no pay off? I want to use the weapons, skills and knowledge that I have gained throughout my playthrough instead of using some hamfisted mechanic that does not really do anything but frustrate the player.
