Sacred Apple
From Dragon Mania Legends (DML) Wiki
Sacred Apples are a resource that can be fed to Dragons to increase their maximum Dragon Level attainable by one, in a process referred to as overcharging.
Obtaining
These rare apples are primarily obtained in Events such as Solo Events, Special Events, or Milestone Rewards Events. They also occasionally appear in bundles in the 
Main Shop or other Shops.
Retention
Sacred Apples accrue as they are collected, and are displayed in the All or Consumables tab in the 
Inventory. The item's Inventory snapshot displays the number of apples possessed, a Use button, and an i button displaying information about the item when pressed. The number of apples possessed also appears when visiting a Dragon in its habitat, as a red 3 notification at the edge of the Overcharge button.
Use
The use of 1 Sacred Apple raises the maximum obtainable Dragon Level by 1; thus, up to 5 Sacred Apples can be given to the same Dragon, raising its maximum level to 125. Sacred Apples are used by visiting a Dragon in its habitat, pressing the Overcharge button, pressing the Overcharge 1 button, then pressing the Confirm button.
Overcharging can also be done from Inventory by pressing the Use button on the item's snapshot, selecting a Dragon (which directly opens the overcharge screen) where the Overcharge 1 and Confirm buttons are pressed to overcharge.
Alternatively, an Element button can be pressed in the Dragon selection screen to filter by Element before overcharging:
Effect
Using a sacred apple does not immediately raise a Dragon's Level, rather makes the Dragon able to be fed past the typical limit. Dragon must still be given 
Food to level up.
Once the Dragon's level is overcharged, the in-game text indicating its level changes to a teal color in all parts of the game interface; this indicates at a glance that the Dragon is overcharged. Like feeding, the process is irreversible once completed.
