Question about giving a unit two similar abilities

I've created two spells based on Doom, each of the two spells should create a different unit, and I've changed them to be unit abilities instead of hero abilities. I created 2 new buffs that are based on the 2 default doom buffs for one of the spells, however when I click on the spell that has the 2 customized doom buffs, the spell that actually gets cast is the spell that doesn't have the 2 customized buffs. This confuses me x_x. Don't suppose anyone has any idea as to why this is happening?

Abilities have an orderstring which they use to order the unit to cast the ability. If you have 2 abilities with the same orderstring, when you try to cast them, only 1 will actually work. Now, the object editor has a field where you can change the orderstring for each ability, but it doesn't work. It only works for the ability "Channel".

Oh! Hmmmmmmmmmmmmmmmmm, I suppose the search continues for a viable way to take control an enemy unit and then create a new unit upon its death. Thank youuuuuuuu for the info ammorth.

Well you can have 2 abilities based on Channel.

Then spawn a dummy caster which casts its own variant of doom .

Wasn't there some hard-coded restriction, which prevents doom to be casted on doomed units? I heard this somewhere...

dummycast one with channel based skill.

parasite does the same thing as doom except it is also auto-cast, you could always use it for the basis of one of your abilities to, and save yourself any coding XD

Try using more triggers in your spells?

Parasite doesn't silence the target.
