Dragon's Tenacity is an encounter power available to warlords at 6th level.
Dragon's Tenacity was introduced in Player's Handbook Heroes: Series 2
CharOp Evaluation: Great [Charop Warlord]
Read the description closely: You don't need to be bloodied yourself to benefit from this power, and it's even better if you're a Dragonborn. And since so many of your powers require you to hit to function, this is probably one of the best options at this level. The fact that this also buffs bloodied allies is almost gravy.
