My pleasure.
There should be a non unique artefact healing afflictions (let's call it amulet of life).
To keep it's attractivity to the chalice and not unbalance the game, this new artefact should be expensive (40 or 80 nature gems ?), useless during battles and have a much lower healing probability than the chalice (divided by 10 ?). OK, Faery Queens are already doing this, but this artefact should work on any unit.
