Hello there! Can I ask for little help here?

I am trying to create an encounter where one enemy NPC heals another in combat. I've created Combat Override Package with UseMagicProcedure. It uses specific spell (HealOther type spell), specific target and condition: GetActorValuePercentage(Health)《 0.7 running on condition target or specific target. And it doesn't work

Did I miss something? And another question on this topic: when does AI start combat override package? When combat starts or it checks conditions repeatedly during combat or maybe EvaluatePackage() is needed here?
