Elements
Each element does more damage to one other element, but also receives more damage from a third element. Fire is stronger than Ice. Ice is stronger than Arcane. Arcane is stronger than Fire. Light and Dark cause more damage to each other. You can use items to improve the stats and resistance numbers of your heroes. For example, placing an Ice item on an Ice Hero will increase their attack or resistance against Arcane enemies. Equipping that same item to a Fire or Arcane heroes will not grant the same effect.
Power Attacks
Your heroes' Power Attacks can be stocked by filling up the meter. This will allow two of three attacks, which are very useful against large groups of enemies or better yet, Bosses.
Upgrades
You will need two of the same item or hero in order to Star Up (upgrade) them. However, they must be of uncommon or better rarity and both must meet a minimum level requirement. The number of stars you can get depends on rarity. An Uncommon can result in 2 Stars, Rare to 3 Stars, Epic to 4 Stars, and Legendary to 5 Stars. Starring Up your Heroes will result in a stat boosts and a new ability. Continually upgrade the buildings in your town to stock up on resources and keep production active.
