DRevans Deathmark in GC broken

Unfortunately in this case the mark is inflicted on themselves indirectly, not by DR directly like Deathtrooper would for example 

Please, enlighten me! Where does it say „the enemy leader inflicts Deathmark on himself“? All I find is: „inflict Deathmark on the enemy leader (…) if Darth Revan is in the leader slot.“

But even if this is true. The task is to „inflict Deathmark ten times“. No matter how, directly or not, as long as it is inflicted it should be fine. But it doesn‘t count if you use DRevan.

It clearly states: At the end of each turn if an enemy fell below 50% health during that turn, inflict deathmark...

Yes it does say "inflict deathmark" though you did not inflict this deathmark, it is a conditional status effect, this means it is applied indirectly so it doesn't count.

I agree with you that this sucks though the text does justify why it doesn't count as you inflicting the deathmark; the effect is being applied as the result of specific conditions being met
