Items are Loot Cards that fall into three categories: Potions, Upgrades, and Artifacts.
Potions are generally instant actions that can heal or aid players in their adventure. Upgrades are useful for enhancing weapons and hero stats. Artifacts serve a variety of purposes, from instant attacks to modifying attacks. Finding or buying loot is what makes the player strong enough to fight more fearsome foes later in the game.
Spell Glyphs are instant attacks. These glyphs are created when sorcerers carve the Eldrich ruins of ancient gods into coins. Their attacks are based on the history and attributes of these gods.
We were going to incorporate armor into the game at a certain point, but found it was too clunky to fit the game. We opted for more upgradeable items than more variety in types of loot.
