[General] Abilities that work during stun?

[MasterWarlord]

I'm just curious if this is possible without making your own stun system. Is there any active ability at all that can be used while stunned? I'm talking about the basic stun produced by Storm Bolt/War Stomp/etc, I use Storm Bolt for all my dummy spell stun needs. What actions can be acknowledged while under the effects of stun?

I am not sure, but maybe Berserk can be used? I remember testing this a long time ago, but then never used it. It was either Berserk or Divine Shield, but I could be wrong...
Try it out?
Make a Neutral Hostile unit with a 5 second stun firebolt or something.
