I have a level 7 town hall and I would like to get a barbarian king. However, I don't have a dark elixir storage. What would happen if I buy a King ? I'm affraid to lose my gem so any advice would be great thanks.
You can buy the dark elixir with real money in the game, by clicking on a pack and purchasing it in the shop.If you have observed carefully, if you have clicked on info button, you can clearly see at the bottom - "NO STORAGE LIMITS". If you are a TH-7 one, by default on upgrading to TH-7 you can store a maximum of 2500 Dark Elixir. You can't store more than 2500 Dark Elixir unless you have bought a storage for it, if you haven't bought any pack.So, you can buy the Barbarian King, if you have enough dark elixir(10000 dark elixir) in your storage.
