Flame Servant Aslan:
Let me tell you how to hatch a Large Draco Egg.
First, it takes a party to hatch a Large Draco Egg.
Second, summon the Large Draco Egg from your inventory. It will appear with a base temperature of 16 degrees.
Third, have the Flame Spirit Agathion use Pa'agrio's Hand to raise the egg's temperature. But be warned! Even the Flame Spirit has a hard time handling Pa'agrio's Hand. The temperature increase may be anywhere between 0.1 - 1 degree.
Fourth, the egg should hatch between 36 - 36.9 degrees with room for failure. It will definitely hatch if the temperature hits exactly 37 degrees. But it will break if you exceed that temperature!
Draco researchers say the closer the temperature is to 37 degrees, the more likely it is to hatch.
Oh! One last thing. When you're in a party, your Draco Egg will be summoned at the same time as your other party members' eggs!
