Always attempt to clear out the level to use your Final Attack. If possible, try to chain all your heroes together for one large attack. For each successive chain, your final attack will be stronger. Note: In order to link heroes together, their circle points must be next to one another. Active skills There is a purple bar displayed below your heroes at the bottom of the screen. This represents their mana. Every time your heroes move and attack, they will charge some mana. Mana charges relatively quickly, allowing you to use your active skills often. Do not save them too long. For example, Clara the Cleric heal skills can help all allied heroes.
