Skills[]

Skills can be broadly divided into three types, some of which have passive effects.

Skill Description
Normal Skill This is each Astromon's basic attack. Its passive effect has a chance of coming into effect when it is used. However, only Astromons 3Star.png and higher gain these effects.
Active Skill This is a skill that can be used when an Astromon's skill gauge is full. It is stronger than a Normal Skill, and can either attack one enemy, attack all enemies, or heal allies depending on the Astromon. Its passive effect has a chance of coming into effect when it is used. However, only Astromons 5Star.png and higher gain these effects.
Leader Skill Only Variant Astromons have a leader skill, which activate when a Variant Astromon is assigned as leader. This skill has no additional passive effect.

Passives[]

Each Astromons Normal and Active attack has an Passive Skill. Passive skills differ from Astromon to Astromon, so be sure to read their Passive Skill's details.

Skill Books[]

Some Astromons' Active and Passive skills can be leveled up using unit-specific "Skill Books." In order for an Astromon to level up its skills it must be a 5Star.png. Not all Astromon's skills can be upgraded using Skill Books.

Skill Books can be found by completing/grinding story regions, special dungeons, and by defeating Legendary Astromons. When using a Skill Book to level up an Astromon's skills, the player will consume the Skill Book and pay a gold fee. There are five levels of upgrades for each of the Astromon's skills. Every Astromon has their skills starting at level 1. When used, one of the skills will be leveled up at random and is leveled up independently of one another (ie. You could have a level 3 second passive and a level 1 primary passive).

They can be received from this specific chest:
