Enhancements: Full Fighter/Lucky/Thief - There are several opinions on Berserker enhancements. Pick the one that suits you.

PvP: Open with 4th skill followed by 1st skill for initial buff and debuff.

The 2nd skill has a quick cooldown and can't miss. Pretty useful if your opponent is dodge-type.

The 3rd skill is a good finisher. It's more powerful when your life is low.
