If Warwick moves to a battlefield where damaged Ahri is defending, does his 'when I attack, kill all damaged enemies here' ability kill her before her 'when I attack or defend' ability reduces his Might by 2?

Ruling: No, Ahri's defend trigger resolves before Warwick's attack trigger, so she reduces his Might by 2 before his kill ability resolves.

Sequence:

  • When Warwick attacks and Ahri defends, both triggers go on the chain
  • Attack triggers go on the chain first, followed by defend triggers
  • Defend triggers resolve first (last in, first out)
  • Ahri's ability resolves, reducing Warwick's Might by 2
  • Warwick's ability resolves second, killing damaged enemies

Nuances:

  • If Ahri had died before her trigger resolved, her ability would whiff (fail to resolve) because it specifies "here" and needs to know the location
  • Triggers exist independently on the chain once created, but location-dependent effects like "here" require the source to still be in that location when resolving
