I would like to add a new mechanic called sustainment. Its like upkeep, except optional.
Shield of forefathers:
11 mana, level 2 Holy + level 1 War, Quick action to cast, Epic. Option 1: sustainment +1
Two Choices:
1: Once per attack, this equipment may absorb up to two critical damage. When there is 10 damage on this card, obliterate it. When sustainment is paid, remove one damage from this card.
2: This mage gains Armor +3 and a defense. Defense: +X, x1 per round, Good against ranged and melee.
X= anything you want Arcane wonders and forum browsers!
PS: you can make something else entirely by adding sustainment to option 2 to improve the Defense.
REPLY ON THIS CARD!
