QWhat counts toward "the number of times your leader has lost defense this turn"?

AFor example, if you deal 1 damage to your leader, that counts. If you give your leader -1 defense to pay for Servant of Lust's On Evolve ability, that counts.

QIf I play Wings of Lust and choose 2 options, dealing 1 damage to my leader twice, does "the number of times your leader has lost defense this turn" go up by 2?

AYes, it does.

QIf my leader hasn't lost defense this turn, but their defense is 7, can I still give this follower +2/+2 with its Strike ability?

AYes, you can.

QIf I attack with Valnareik, Omen of Lust, do I resolve her Strike ability before my opponent can play cards or abilities with Quick?

AYes, you do.
