Since Cotillion is being coy about what Muscle Armor does, I'll explain.

Muscle Armor is an aura for unarmed/armed users that gives good stats (don't remember the specifics), with its main draw being its Q ability.
It is a temporary CC immunity to everything. Can't be rooted, stunned, blinded... Not even knockback works, so moves like javelins and dragging beams won't stop them.
The only way to properly avoid a melee user with Muscle Armor's Q ability up is either by using speed boosts or by turning on invulnerability. Otherwise? They are going to go in, and they'll hit hard.

It is a strong ability in an aura that makes it worthy as a hidden ability. Can literally turn battles around and make certain match ups turn into the armed/unarmed fighter's favor.

30 pow, 10 vit, 10 seconds of : CC, and Knockback imunity.

No slow imunity, no root imunity. if you wish that, you need combo with warcry then you have 4 seconds of full imunity, nothing else.

The thing is, is a full counter for full based stun builds, oh it also make strike and jab, have a chance to cause a 1 s slow.

Is too good to be a public master, so as a signature? is fine, it adds the exalted tier of dificultie to get. remember is a aura active you still can combo with whatever you stance have.
