Why is there a droprate for certain items?

Hi Hero,
We can understand that it can be frustrating when you do not receive a particular item that was advertised in the game/chest.

However, please note that we have to give a level of rarity to some items, as they are too powerful. If everybody received them, it could heavily influence your game experience and therefore your daily enjoyment of the game.

All the very best,
Your Gaea Support
