I'm trying to make a list of known-abusable spells/feats/PrCs/items/etc. or combinations of those in 3.5. "Abuse" is a controversial word for it, because it's perfectly legitimate to run a campaign where powergaming is encouraged, but what I'm basically looking for is ways that a character can become far more powerful than any well-built core character. Of course characters using non-core materials can be more powerful, but usually it's many incremental differences (which can add up to a lot) rather than individual effects that dramatically change the character's power level. I'm looking for the things with those individual, dramatic effects. I'm also considering only 3.5 sources, so no BOED, BOVD, etc.
A short list to start out with:
Divine Metamagic, when used to cast effectively-over-9th-level spells.
Wraith Strike with Persistent Spell.
Polymorph or similar effects used with non-core monsters. e.g. War Troll or Kelvezu. I'd actually also put one core monster in this category -- Hydra.
A Thought Bottle used to erase the XP cost of Wishes, magic item creation, etc.
Eventually I'm planning to come up with a minimalist set of house rules that would address these things (which I'll post under house rules), but for now I'm just trying to figure out what's out there to be addressed.
