Healers can heal during the fight. Just not revivals on the field of battle. No rezzing heroes or dead troops behind an advancing army mid fight. That sort of deal.

And yes, lower the steel skin. Armor has joints you can take advantage of, it is also cumbersome. Making the whole body steel doesn't afford those weaknesses. Therefore, arrows glance off, swords glance off, and ideally the only way to kill it is by jumping into its mouth and suffocating it. You see the dilemma. I saw the intent, but we still have to make it fair.

Should be good to go. Approved.
