[D&D 3.5] Heroes are Made, not Born

[The Rabbler]

Just to make sure I understand this correctly, we are not allowed to multiclass before we finish buying off our warrior/expert/adept levels, right?

EDIT: might as well throw out some less-relevant questions.

would you also allow the Mantled Warrior ACF (I ask because I like having options )? it can be found right above the soulbound weapon ACF here.

can specific feats be allowed into the campaign if they're not from the allowed books? I don't want to destroy the campaign or anything; I just think that tashlatora might be fun to have around/available.

and what are your feelings on somewhat-obscure PrCs? I was looking at Ghostbreaker and it sounds like a lot of fun. possibly useless, but fun nevertheless.

EDIT2: It's from Hyperconscious. a Swords and Sorcery book. . I guess that rules it out.
