3 different stomp abilities? (thunderclap,war stomp and need 1 more)

the idea is that the cooldowns should not stack.if i create 2 thunderclap abilites,the cooldown will stack.Same with the war stomp.The ability should just do damage to some units around the hero caster.no need of slow and stuff.

Create a custom Channel ability and customize it to make it look like what you want (War stomp). With triggers, on cast event (The unit starts the effect of your custom channel ability) create a dummy and order that dummy to do the real stun you want.

Be aware that Channel has a "Base order ID" data field, that must be different than any other ability the unit has.

I don't think there's any other Wc3 default Stun other than War Stomp.
