Roar of The Tiger: Like I said level this up ASAP. Always use this SilkRoad online Gold in HH, FB`s, Luring for AOE parties at wolves or spiders, or even for running forest ruin.
Raging Bite: This is your main aggro tool. Keep this at the highest possible level. This is also a fair bit of damage too seeing as you can stack it.
Wrath of The Tiger: This is a great skill; Make sure that when fighting bosses you time it correctly to cancel their skills. Especially on higher level HH or FB bosses like asura and you can save your hero.
I suggest keeping this at a moderate level since the skill cancel is effective at any level of the skill but it does do fairly decent damage.
Tigers Maw: This is a pretty helpful skill, but the only problem is that it will cost you 35 chi to use it. So the only time you should really be using this when in a party fighting bosses.
If the WF doesn’t have their armor break at a decent level and is willing to use vigor transfer on you so that you can use veil of shadow or sundering heaven.
