When a Leadership ability is used to apply a debuff to an enemy, I assume Potency is needed. But whose?
For example, Datcha's Decommission ability reads (at level 1): "Whenever an Ally damages a Droid, there is a 50% chance to inflict Defence Down for 2 turns."
Assuming the 50% chance is passed, whose Potency is used to calculate if the target resists? The wording of the ability doesn't say it's the Ally or Datcha who is trying to apply the debuff; it just says "there is a chance to inflict".
Compare that wording with Chief Nebitt's Raiding Parties ability (at level 1): "Jawa and Droid Allies ... inflict Critical Chance Down for 1 turn on a Critical Hit".
That wording is a bit clearer in that it says it's specifically the Ally and thus, I presume, the Ally's Potency is the relevant stat.
But the wording of Datcha's and others are not so clear. So is it always the Ally's Potency or does it depend on the Leadership Ability in question or what?
