Lichdom

Prerequisites: 16th level wizard, Magic Jar spell, Animate Dead spell, Geas spell

To add this feat, you must do the following in order:

1. Cast Magic Jar
2. Cast Animate Dead  on your body
3. Cast Geas on your body
4. Posses your body
5. Perform a ritual that takes 8 hours to turn your jar into a phylactery

When you complete this ritual, you gain the statistics of a lich, although you retain your alignment and personality. However, you begin to feel an increasing pull towards evil. Every day, you must make a CHA save with a DC equal to 1 + the number of days you have been a lich. On a failure, you become Neutral Evil. If you roll a nat 20, or if you make 20 successful saves, you don't need to make these saves for 1d4 months.
