Help with the Bear

[Havriel]

Im gonna play caelics build bear of the north but i gotta make few changes because tome of magic is dissalowed

the build goes like this Class/Level: Cleric 1/Paladin 2/Fighter 2/Chameleon 10/Witch Slayer 5

so i was thinking going with crusader in place of the witch hunter

edit : all other books are allowed and i just need replacement for the witch hunter prc and maybe pally

Fighter 2 is a waste if you're going to be playing a high level build. While helpful early in your progression, extra Feats are eclipsed by better class abilities later in your progression.

Also, are actually playing to 20th level? Because if so, any half-caster class or PrC like the Chameleon is a bad idea. You'll still be stuck on 5th level spells when your party members are rocking out 8th and 9th level spells.
