In what order do dragons attack in a Dragonfire fight?

Dragons don't all act at once: they play in an order set by Initiative. The more Initiative a dragon has, the earlier it acts in the round.

Why that's crucial: hitting before the enemy means stripping its troops before it can answer. Over 10 rounds that small edge compounds enormously. A fast dragon weakens the opposition before it has even played.

How to raise your Initiative:

• The First Flame research (raises Initiative across all your dragons).
• Certain auras (a Warrior's Battle Rush at the Center, or Champion habits like Wind's Favor).
• The dragon's level.

Careful though: Initiative has a double role. It sets the order and it reduces the fire damage you take (see the stat triangle).
