I'm going to be joining a pbp game of Hell's Vengeance and have gotten approval to play a character that is working toward becoming a lich.
The GM has also approved using the Eternal Apotheosis ritual from Occult Realms, which uses the Ritual rules from Occult Adventures.
I'm looking at using the Agent of the Grave PrC, my primary reason for this will be the additional spell access and bonuses on the Ritual.
The one wrench I'm throwing in to the build is I don't want to be a necromancer, just a powerful caster that want's to live forever. Possibly an enchanter or charm focused sorcerer. (Though I'm open to other ideas)
Any Paizo books / classes allowed, most races will be ok as well. We will be doing 20pt buy.
Thoughts, suggestions and ideas would greatly be appreciated.
You don't need to be a necromancer to become a lich, you just need access to certain spells. Even agent of the grave only requires the ability to cast animate dead (a 4th-level sorcerer/wizard spell, so minimum wizard 7 or sorcerer 8 before entry), not that the character creates undead regularly; the 1 year as part of an undead worshiping cult can probably be added to the character's background, if the GM agrees, rather than needing to spend a year of game time after 1st level.
Note that even if you choose Necromancy as an opposition school for a wizard, you can still prepare and cast Necromancy spells by using two spell slots instead of one.
Occult Realms has a ritual for becoming a Lich called Eternal Apotheosis, Tammy's going to use that.
