artifacts and heroes on mount

[rion82]

how does artifacts like Hydroxskin Cloak(relic of chamon),Thermalrider Cloak(relic of aqshy),Doppelganger Cloak(relic of ulgu),Sash of the Ten Paradises(relic of hysh) and Gryph-feather Charm(relic of ghur) works on heroes on mount?

they're all artifact that modify the movement(apart one but the question is the same),so had they affect on the entire model or hadn't they affect at all?

[King Taloren]

They affect the whole model. The only thing that was made different was command traits don’t affect mounts which they have a mount trait for. 

[rion82]

thank you very much!

[Choombatta]

Artefacts of Power have no effect on attacks made by a hero's mount, but only attacks.

Command Traits have no effect on attacks made by a  hero's mount, unless noted otherwise.

Battle Traits effect everything with the correct keywords.
