Sisyphus should offer more Darkness

[Anderson]

As it stands, if you don't need the heal, the choice is either 100+ gold, or 15 darkness or so. Needless to say, the choice is pretty obvious, and gold is better 100% of the time. While I understand that these amounts are equal to what a pickup would be, Gold is offered alongside boons and poms of power, while Darkness is a "here is something while you wait for another Boon" resource, which is far less necessary.

Could we raise the amount to, say, 50? Or even more? Treasure Troves start at 150 (Same as gold), so this encounter should offer a comparable reward (given how powerful Eurydice and Patroclus are)
