The Dhunian Archon has the rule (CID still, it may change) Threads of Life - Once per turn when a friendly non-warlock warrior model in this model's command range is disabled, this model can suffer d3 damage points to remove 1 damage point from the disabled model.
Does this have devhost implications? Morv1 with recursion and armour buff from restoration along with the archon could provide a spicy brick problem?
Protecting brighid/caul/lotf might be useful. As far as the brickiness goes, one extra guy living a turn isn't a big deal. But protecting what are some if the strongest warrior models in the game could have some use. Especially with Grayle when every random tharn ravager is a threat and any one of them can kill a low camp caster.
