Buy credits
One hundred credits cost a single dollar, and they arrive on the character you choose the next time that character logs in.
How delivery works
You enter the name of your character and how many credits you would like, then choose to pay by card through Stripe or through PayPal, whichever you prefer, and the moment the payment goes through the credits are waiting for that character, ready to be picked up the next time they log in.
Credits buy extra characters and items from the shop, and nothing they buy ever decides a fight, so there is no pressure to spend and no advantage in doing so, only more room to make the world your own.
If something does not arrive, open a support ticket by pressing control shift S in the game, mention your character name and the payment, and we will sort it out.
