Using wishes has long term consequences...

This is a twist on EvilHack's monster generation, but instead of basing the generation on game landmarks - it's based on the number of wishes the player has made.

1 wish = 2x the rate.
2 wishes = 4x the rate, then 6x, and so on until it's capped at 10x.

The overall difficulty of new monsters is also increased for each wish. I hope this offers a challenge while letting players have the freedom to choose their fates. If they choose wishless, the endgame should be a decent bit easier (potentially eliminating the need for some wishes), but the player might also want to wish up a furious late game challenge on purpose, who knows!
