The battle screen is divided into two parts. The player's part is a board covered with Runes of various colors that represent the following elements:
- Yellow — Light
- Purple — Darkness
- Blue — Ice
- Red — Fire
- Green — Nature
To attack, slide a Rune to make a vertical or horizontal row of at least three Runes of the same color.
A four-Rune row will leave a Bomb that explodes and activates nearby Runes (regardless of color) after tapping it.
A five-Rune combo will leave a Crystal that activates all Runes of the same color (regardless of their position on the board) after tapping it. Those two effects may be combined to create an even more powerful attack.
Each of your Heroes has a certain background color that matches the color of a Rune. After several successful attacks with the matching color, a Hero gains Mana. As soon as the Mana bar is full, that Hero can use their special ability. To activate it, just tap on the Hero avatar or select a certain enemy for a targeted attack.
