Can I spend my Defiance to refresh Pardon in the middle of getting Defiance from overhealing during an Objection (or Judgement)?
In both cases you can. Everything in Raid Boss is sequential and on a stack.
- When breaking down area of effect or multiple target abilities, they always trigger in turn order starting from the active Hero.
- So each time a Hero is healed, you can technically step in and pay Defiance (or use other Instant abilities) so as not to waste your precious Skill!
