Umbra armor

Totem Armor is a keyword ability introduced in Rise of the Eldrazi and appears on Aura cards. If a permanent enchanted by an Aura with totem armor would be destroyed, instead the Aura is destroyed. If that permanent is a creature, all damage is removed from that creature. In this sense totem armor works similar to Regeneration.
