Skills
「Fire Wyrm LV10」」►「Fire Dragon LV10」►「???」

All wyrms have a Wyrm skill, and all dragons have a Dragon skill.

As the Fire Wyrm skill increases in level, it grants new abilities:
 * Level 1: Fireball Breath
 * Level 2: Heat Wrap
 * Level 3: Life Exchange. Recovers HP by consuming SP; Dragon Scales
 * Level 4: Flame Breath. Spews flames over a wide range.
 * Level 8: Flame Wrap. Wreathes the user in an intense blaze, improving physical abilities.
 * Level 10: Inferno Breath

Before level 10, Light Wyrm grants the Humanification ability, which gives the user a human body to match their mind.

「Dragon Scales LV10」►「Imperial Scales LV10」►「Divine Scales LV10」

The Dragon Scales skill is awarded by evolution to Catfish and upgraded to Imperial Scales in Gunesohka. The only known holder of Divine Scales is Araba at level 32.

The Dragon Scales skill causes scales to grow over the creature's body, increasing its defense and resistance abilities by directly interfering with the composition of magic. . Imperial Scales is simply a stronger version of the same effect. On Sophia, Divine Scales has the effect of growing white scales on her body.

「Wyrm Barrier LV10」►「 Dragon Barrier LV10」►「Divine Dragon Barrier LV10」

These Skills produce a barrier that has similar properties to Dragon Scales. They can be obtained by non-dragons that have killed a wyrm.

The Divine Dragon Barrier is strong enough to even hold back Ariel. Six of the nine earth dragons of the Bottom Stratum have the skill.
