Whether it is Water, Fire and Earth from the nature; or Light and Dark from Gods and Demons. All Attributes are mutually exclusive.
Taking the advantage of opposing Attributes, clearing up enemies becomes much easier.
Exclusive in nature
Water quenches Fire; Fire incinerates Earth; Earth eases Water; while Light and Dark are mutually exclusive. Attack will be doubled by dissolving the opposing Attribute, otherwise the attack power will be halfed.
The nature of opposing Attribute strikes a balance between the power of Dark and Light.
Monsters could get Level-up when merging with other Monsters. Level-up will be stronger when absorbing Monsters of the same Attribute. Therefore, Summoners should fully utilize Monsters of the same Attribute to make Level-up more effective.
Level-up can enhance Monsters’ ability.
The level of Active Skill will affect the number of Rounds in Battles. To initiate Active Skill more frequently, Summoners need to get Level-up on Monsters’ Skills. Besides participating in more Battles, merging Monsters with the same Active Skill (during Monster Level Up) can have a chance to gain more EXP and make Skill Level-up more effective.
Using monsters with same skill for Level Up can increase skill level.
As Monsters Level max, specific Materials are required to Evolve. After Evolution, Monsters will adopt a different outlook but their Levels will return to basics while most of their levels of Ability will remain unchanged.
After evolution, some Monsters will have stronger Active and Leader Skills.
