Loot

The center pile of a players board consists of loot cards which also functions as the player's health.

When an enemy unit reaches the center of the castle an number of cards equal to the unit's attack value is removed from the pile and given to the owner of the attacking unit.

These cards come in two types, Bonus Gold cards and Upgrade cards.

Gold Cards
Gold cards can be played instantly when received or played during a player's turn like a normal card if the player wishes. It should be noted that the card does count towards the player's total amount of cards on hand. The cards give either one or two extra gold to the player depending on the individual card.

In the deck there are six cards which gives two gold and six cards which gives one gold.

Upgrade Cards
Upgrade cards are added to the players hand and counts toward the player's total amount of cards on hand.

These cards can be played during the player's turn to upgrade existing base towers. When upgrading a tower the player pays the price value of the upgrade card and places it on a basic tower, any damage on the basic tower is carried over during the upgrade. The player may not place more than one upgrade on a single tower and may not place an upgrade in a slot without a basic tower.

There are three different types of upgrade cards.
