King Ragnar Dragon

Detailed Explanation:

Effect:

The skill's damage output is directly proportional to the amount of damage the user has received. The more damage the user has taken, the more powerful this attack becomes.

Example:

If a dragon uses this skill after taking 800 damage, and the skill deals 150% of the damage received, the dragon will inflict 1200 damage on the opponent.

Pros:

- Strong comeback potential when the user has taken significant damage.

- Can turn the tide of battle in desperate situations.

- Encourages strategic play where the user might risk taking damage to unleash a powerful attack.

Cons:

- Risk of knockout due to low health, as the user needs to take damage to increase the skill's effectiveness.

- The user must survive long enough to take advantage of this skill, making it a high-risk, high-reward strategy.

- Less effective in the early stages of battle when the user has not yet taken much damage.
