Polymorph

From Neverend

Lycanthropy changes one into a half human, half creature.

Shapeshifting can change to a completely different form, such as a full animal. This allows animal specific attacks such as claw and bite.

Summoning an animal will create an animal or magical creature to help you. Using an item can summon some magical creatures, such as magical lamps or bottles, or a mage can use a spell. Rituals work similarly.

Spells and items that do not summon a creature to your aid may summon a creature to deliver a powerful attack or healing spell before dissapearing.

Taming an animal will cause specific creatures to help you fight instead of harm you or run away.

Mind controlling or possessing an animal will cause to follow your directions, such as attack, move, open, take item. You may be able to have direct first person control of it as well. Controlled creatures have about four available commands such as slash, claw, bite.

Typical animals to possess, tame, shapeshift into, or have a were form include:

Wolf Bear Rat Cat Bat Giant Spider Tiger Lizard Dragon

Non-animal forms are usually monsters or magical creatures, such as Vincent's form in FF7. This includes unique looking monsters that resemble behemoths, demons, or other creatures.

Magical forms look like fire, ice, water, wind, lightning, or ether elementals. They can also be a statue resembling stone or metal. A magical aura can surround a player to indicate they have turned into some magical form.
