From Dragon Mania Legends (DML) Wiki
Divine Wisdom can be learned by all Divine Dragons. It is an active defensive skill that applies a positive status effect by increasing the health and attack for two turns.
The health and attack increased by Divine Wisdom is not affected by Dark Clouds or Shade of Oneself. Additionally, this skill does not amplify the effect of other skills. Once this skill wears off from a Dragon with low health, that Dragon will not faint as the remaining health ratio will stay the same and adapt to the Dragon's original stats.
This skill can be used multiple times, but only the duration is prolonged.
An ally deals more damage and has more health for 2 turns. Skill effectiveness is based on caster's Dragon's Attack Strength (DAS)
