Fanatism aura + CTA Buff

I have a A2 Might Merc, a Beast

Axe as main weapon and a CTA in weapon swap. Wonder if CTA Buff, Fanatism aura and Might aura will be stacked, because if war cries from CTA are active I can't see the aura on skeletons.

Yes, they all stack.

Your CtA buffs will affect everything in range when you cast it and will last for their duration.

The merc's might and your Beast's

Fanaticism will affect everything within aura range of your merc/yourself respectively.

However, the

Fanaticism buff will only be there while you have Beast actively equipped. So if you switch to CtA to buff, fanaticisim will be turned off until you switch back to Beast. That's true for auras in general.

Shouts are actual cast buffs though, unlike auras, so they remain for their duration even after you switch back to Beast.

That having been said..once you get enough auras, shouts and whatnot all overlapping, it gets hard to still actually see each individual one.

Thanks Schnorki for this detailed answer. That it all works together was my intention and now I can even see all auras and casts together.
