Favorite Polymorph Self Forms?

[Azure Trance]

Hill, stone, frost and fire giants are also some very nasty possibilities. Most of them are especially good for a character in heavy armor, since their low Dex isn't a problem in that case.

From what I understand of the spell, polymorphing to a large form which can use weapons will also increase your weapon size for that duration? (i.e, that long sword just became a large longsword -or greatsword?-)

The revised version of polymorph from T&B places a HD limit equal to the greater of the HD of the caster or the recipient, with a max of 15HD. The revised version also doesn't allow you to switch forms as a full round action, your stuck with the form you morph into short of casting it again.

Though personally I would let the psions keep the version in the PsiHB just for variety and because in general psions are a little weaker.

Actually the most recent version of Polymorph Self can be found in the Psionic's Handbook errata at

This version does limit the forms by hit dice....

That's right. For the morphed character, the longsword is still a longsword. For his companions (and enemies), it's more like a greatsword, and deals a higher amount of damage.
