Each Character has three skills with two upgrades each. In the beginning of the game, the players only have one skill per character. New skills can be found as the players progress in the levels. Killing monsters gains the players experience, and when the experience reaches a new level, the players can use skill points to buy new upgrades for the skills they have. Click on the skill that is wanted to upgrade to gain new enhancements to the skill.
During the course of the game the players may also find items that give special enhancements to the characters. The players can move items from character to character by clicking on the Item and then clicking on another spot in the Inventory Menu.
