CIS durge abillity timing

cis durge is on 1 hp
gets 3hits
does he have to resolve his ability after the 1st dmg card?

It depends on the situation:

• during an attack, Durge's ability resolves at the Aftermath step, after all damage cards have been dealt.

• when damage is dealt by anything different from an attack, the ability is resolve after the first damage card. The remaining damage cards are dealt after the resolution of Durge's ability.
