{{stub}}A Player may sell a defense by pressing Z (by default) and then left clicking on the defense. A Defense will sell for [[Green Mana]] based on it's condition and upgrade status.A Defense sold in the same build phase it was built in will give a full refund, including any [[Green Mana]] spent on upgrades.A Defense sold at any other point after it has been built will sell for 75% of it's cost (Including Upgrade costs) times it's percent health left. Example: a [[Flameburst Tower]] costs 40 mana, if it is sold at half health you will get 11 mana back, 30 mana * 75% * 50% health.
