Nightmare's Isekai

This mod is used to be able to reintroduce the beloved isekai feeling into the world of Tensura.

Features:
- Every base tensura unique has been mapped to an advancement
- Undead muggers have a 12% chance to replace a zombie and glow red
- Until death by a mugger you are in a world where tensura has no impact
- Unable to get above-diamond weapon/armor
- No tensura or tensura_neb bosses spawn
- Cant gain any skills at all no matter ep count until you reincarnate
- Command to generate a list of all advancement and uniques
- Easy config to follow to add custom uniques to the pool or modify existing reqs
- Dying to a mugger with no skill-granting advancements pulls from tensura's configged list but you lose out on the control of aiming for the skills you want
- Compatible with reset counter bonus
- Drop-in ready for any server, only affects character resets and first joins and the no-advancement still allows modded skills if you dont want to make a config and makes them rarer at that since you cant specifically aim to get one if its not in the advancement list
- Lots of detection to prevent reincarnated and non-reincarnated being in the wrong dimensions
