Regrow a Limb

I have done some research about regeneration and regrowing body parts in the rules.

There are some options, although I would say none of them seem to be really that easy to get a hold of at the current game level.

Trollshape spell from the Player's Handbook II page 127. Sorcerer/Wizard 4. It changes the caster into a troll (including regeneration) for 1 round per level. That's not long enough to regrow a limb.

Shapechange spell from the Player's Handbook. Sorcerer/Wizard 9, Druid 9, Animal domain 9. It can change the caster into a troll (or other regenerating creature) for 10 minutes per level. This would help to regrow a limb, but the level it very high.

Regenerate spell from the Player's Handbook. Cleric 7, Druid 9, Healing domain 7. Instantly regrows missing limbs but the level is very high.

Troll Blooded feat. This would let you regrow a limb in 3d6 days.

Considering there is so few ways to get the regeneration special quality, and they changed Monstrous Regeneration to Greater Vigor in the Spell Compendium (making it fast healing instead), I thought I would simply restore the Monstrous Regeneration spell back to the game, and update it to 3.5 for my games. I have included it below and also added it to the Libram of Magic III. However, even this spell it is hard to accomplish, but not impossible at lower levels.

Most creatures that have regeneration do not regrow limbs (looking only in the Monster Manual). Angels, Devils, Ogre Magi, etc do have regeneration but do not regrow limbs. Trolls (3d6 minutes), Chain Devils (2d6x10 minutes), and the Tarrasque (1d6 minutes) do regrow limbs. In consideration of this fact, and also the fact that the spell has a very low duration, even giving it Tarrasque regeneration would not have enough time from the spell unless the caster were 20th to 120th caster level (for 1d6 minutes of regrowing). So I would liken the Monstrous Regeneration spell to an ogre mage's (and angel's and devil's) regeneration ability that does not let it regrow limbs.

For the purposes of this spell, I would consider the bite attack a single limb, not 30 individual teeth like a tiger normally has.

Monstrous Regeneration

Updated from Magic of Faerûn, D&D 3.0 edition.

Conjuration (Healing)

Level: Cleric 5

Components: V, S, (optional Metamagic Component)

Casting Time: 2 full rounds

Range: Touch

Target: Living creature touched

Duration: 1 round/2 levels

Saving Throw: Will half (harmless)

Spell Resistance: Yes (harmless)

            You give the target the regeneration ability that some monsters possess (see below).

            The target cannot regrow missing limbs with this spell (however, see the Metamagic Component entry).

            When the spell ends, all of the target’s nonlethal damage is converted to normal damage.

            Regeneration (Ex): The target recovers from wounds quickly and can even regrow or reattach severed body parts. Damage dealt to the target is treated as nonlethal damage, and the target automatically cures itself of nonlethal damage at 4 hit points per round.

            Fire and acid deal damage to the creature normally; that sort of damage doesn’t convert to nonlethal damage and so doesn’t go away. If the target has been rendered unconscious through nonlethal damage, it can be killed with a coup de grace. The coup de grace attack cannot be of a type that automatically converts to nonlethal damage.

            The target can reattach severed limbs or body parts. Severed parts die if they are not reattached.

            Regeneration does not restore hit points lost from starvation, thirst, or suffocation.

            Attack forms that don’t deal hit point damage ignore regeneration.

            An attack that can cause instant death only threatens the target with death if it is delivered by weapons that deal it lethal damage.

            The target must have a Constitution score to have the regeneration ability.

            Metamagic Component: An eyelash or toenail removed from a troll within the last minute (or currently under the effects of a gentle repose spell that was cast on the body part no more than 1 minute after harvesting); grants the target the ability to regrow one limb in 3d6 rounds under the effects of this spell (although the spell still may not have enough duration to regrow the limb).
