We all hate HETE. Universally.
Their costs are prohibitively expensive.
Perhaps, a new minor artifact can be introduced, HETE Insurance Token which drops randomly in-game and can be redeemed against a single cloning incidence. Potentially, they can be traded between players, until you decide to lock it towards your own redemption.
In order to avoid an abundance, perhaps once you get one, you cannot get any other, until you use it up or trade it to another (transferable only once)
