When you combine 3 or more elements (called Runes) of the same color you will add Attack Power to the corresponding element of the character on your team. Take into account that if you clear runes of an element that is not on your team, you will not gain any attack power.
If you chain together 4 or more Runes of the same element, it will create a Spell Rune (Bomb, Slash, Bolt runes).
Spell Runes can create Chain Combos. When a Spell Rune effect hits another Spell Rune, it will create a chain, causing you to increase your Attack Power.
Types of Spell Runes:
- Bomb
- Slash/Cross Slash
- Bolt/Bigger Bolt
