Custom ability: Active dodge

[:1]Hi there.

I'm trying to design an ability for a custom hero. It should give him 30/60/90% dodge for 5 seconds.

I first tried to change the demon hunters ability to be active, but I couldn't figure out how.

After that, I tried to change the demon hunters immolation, but unlike its evade, it doesn't have an option for "chance to evade". The same problem applies to windwalking and similiar self-buffs.

Also, I couldn't find an option to add these, nothing in the triggers and, to me, the buffs seem to be mere symbols to indicate the buffs.

I'm stuck here.

Thanks for your help.|||See Unit - Add Ability.
