Shout. All allies within earshot that are below 50% health gain an additional 40...150 health and +10...20 armor for 3...8 seconds. Allies under 25% health are also healed for 10...50 health. (Strength).
Just to keep the battle going with things like Defy Pain and Watch yourself...
Maybe this is a tanking skill... no way.
Well.. it could be for 5 seconds...
Anyway, start big, then grind it down...
so then.. 5 seconds, reduce additional health to 100... maybe no healing at all..
