Possibly, sure. Really depends a lot on how your team is doing more generally. If you have Conellia booked, you might be able to just have her keep using her A3 on Armiger to keep him alive - but that's requisite upon Armiger actually surviving long enough to be healed, and then surviving long enough to have the cooldown reset on the heal so he can be healed back up.

well i also have urogrim for healing. i think itll work out
