Which dragons should you spend Legendary Cores on in Dragonfire?

Legendary Cores 🟡 only upgrade the habits of Legendary dragons — they're rare and precious. Don't spread them around.

Concentrate them on your key Legendaries, the ones you actually play and whose habits weigh the most:

• go first for their set habits ⭐ (the ones that reinforce the Order) and their 5th habit (the strongest one),
• favour a dragon you field at the Center (the aura hub) or a team amplifier.

Why concentrate everything: a finished Legendary — stars plus raised ⭐ habits — is far stronger than its raw Power 🔥 suggests, and it's permanent. One finished Legendary beats three half-built ones. Rare 🔵 and Epic 🟣 Cores go to dragons of the matching rarity.
