expand_less These are just a few notes explaining the tier rankings and other considerations for binders. Binders were originally introduced in Tome of Magic by Wizards of the Coast for D&D 3.5. They were updated as Occultists by Radiance House in a few books for Pathfinder (not to be confused with the class in Occult Adventures). These characters bind otherworldly entities and gain a portion of their power. These powers are quite diverse, allowing for a great deal of versatility, but not nearly to the degree of spells. As a result, Binders are tier 3 and Occultists are tier 2.5 (due to some power creep). The Zceryll vestige is particularly strong, and warrants a tier increase. Players can choose to remove Zceryll from their lists of vestiges / spirits, and remain at a lower tier.
