One life, and we price that in
There is no resurrection on a Hardcore realm. A character that dies is gone, with everything on it, and no order we could run would give it back. So the levelling here is slower than Classic Era on purpose and costs about a third more: the booster is pulling one mob at a time, stopping to eat, and skipping the quests that kill people. The premium is the caution. Anybody selling you a fast Hardcore level is selling you the risk.
If we kill your character, you get your money back
The death guarantee is an extra and it is the only promise on this site that covers an outcome rather than a delivery. If your character dies while a booster is playing it, the order is refunded in full. We would rather price that in honestly than write a page that implies it cannot happen.
Self-found changes what is possible
A self-found character cannot trade and cannot use the auction house, so nothing can be bought for it and nothing can be handed to it. That makes every service here harder rather than easier, which is why it costs more rather than less, and it is why the gold service does not apply to self-found characters at all. If you are self-found, say so on the order.
