LokiDR said:They have never done that, even in 3.0. There were numerous 'clarifications' published in later books. Tomb and Blood went so far as to reprint polymorph, again. Wizards has used the extended material to clarify the game several times (and sell more books). I fail to see why this is different.
When they reprint something, the newer version always takes precedence. Outside of the core books, this has always been spells, feats, or a specific prestige class.
I can't recall when a non-core book has changed one of the core rules.
This may be the exception, but you would think they would spell it out. Or at least be consistent. The most recent Complete book (Complete Adventurer) does not have this rule. Does that mean the rule has been removed?
