I wish for eventual greatness - Take a -30% HP, FP, and Stamina debuff that lasts for the rest of the day. After that debuff expires at the start of the next day, gain a +20% HP, FP, and Stamina buff permanently. If you die before any of that happens, all aspects of this deal are cancelled.

Take improved physique - A variant of the above, but without any debuff. This is only available if the run was invaded and Libra was paid off.

I want a lot of runes - Places the Symbol of Avarice in a vacant talisman slot, at the cost of 10,000 Runes. If both talisman slots are filled, you have to pick which talisman to drop in order to receive it. Available only during days 1 and 2. If the run was invaded and Libra was paid off, you do not pay any runes.
