Other than fatigue (30) and ap (3) costs indomitable is rather clear: 50% dmg (I assume both armor and hp, since not stated otherwise) and immune to stun. I find it rather dubious due to high fatigue cost.
Taunt is completely opaque, agree on that one. Question to those who use it – can it be used to force enemies to kill themselves by attacks of opportunity (that is Taunt by far-away bro, while enemy is engaged by multiple bros already)?
