Play as Ender Dragon - Dragon Survival Addon

Features:

• Armor, trim and claw item textures.
• 3 new skin parts: teeth, wing bones (you can adjust their color separately from the wing) and enchanted claws.
• Russian translation (thanks to WhyVernAD).
• Polish translation.

Balances:

• Increased base flight stamina by about 25%.
• Dragon hearts are now better at granting growth progress, but doubled the time for the last stage.
• Enderman reputation regenerates 2x faster and bad reputation has a 2x smaller cap.
• Nether stars and enchanted golden apples now grant positive effects when eaten.

Other:

• Tongue is now classified as an extra part rather than teeth.
• Optimized fireballs (yet again) for approximately a 5x performance boost to damage clouds.
• Endermen are also optimized quite a bit in terms of handling the reputation system.
• Minor model/animation changes.
• Also if you'd like, there's an optional datapack on github that allows you to eat meats and fish (if you want easy mode).
