Amended.
I decided to remove Dispater and the other archdevils, on account of being only accessible to one PrC, and have added the PrC to the list instead.
The WotC Vestiges in posts by "zombiegleemax" will be marked as "by Anonymous".
Simply missed it. Will add.
Y'know, thinking about it, I've never seen a homebrew base class that uses binding. Well, other than the Dabblemaster, but that one is a basket case.
Also, there are currently several threads about making Tier 1 mundane classes, most notably by Ziegander as an outflow of Grod's, which is a twist on his earlier Legend classes (one which is mostly a Fighter Fix, and a later one that is a High Tier 3 combatant). Right now I'm unsure whether they are Tier 1 as aimed for, Tier 2 due to lack of extensive content (might not be necessary to make it Tier 1) or High Tier 3 due to lack of gamebreakers/single-round encounter-enders.
