This page of the Divinity Original Sin 2 guide contains a detailed description of Polymorph magic school. You'll learn what kind of magic the school is characteristic for, what spells can you utilize and their effects.
Polymorph abilities allow you to inflict many negative statuses on enemies but also strengthen your character by increasing physical armor or giving an ability to fly on a battlefield. It is great for melee-oriented classes, especially those that rely on Strength such as Fighter or Paladin. In addition to that, each point invested in it gives that character 1 extra Attribute point.
Warning - if you have problems with finding traders that offer a particular skill book, you can check the chapter with maps of Fort Joy, Reaper's Coast, Nameless Isle and Arx where you can find locations of all traders in the game.

Apotheosis - lowers Source Points cost of all abilities by 3 for 3 turns.
2 Memory
3 AP
6 turns cooldown
If used well, this ability is one of the most effective in the entire game - it allows you to use the most powerful abilities without any problems because they will cost 0 SP for 2 turns.
Bull Horns - gives 1 point to Retribution and allows to use Bull Rush ability.
Incompatible with Medusa Head ability.
1 Memory
0 AP
6 turns cooldown
An interesting ability that costs no AP - however, Bull Rush requires 1 point. Bull Rush itself is one of the most unique abilities in the game - you can charge at an enemy and deal Pure Damage that breaks through both armors.
You should use this ability until you unlock Spread Your Wings.
Chameleon Cloak - casts Invisibility effect on a character.
1 Memory
1 AP
6 turns cooldown
A powerful ability that is especially useful to archers and assassins. Thanks to it they can easily (and at a small cost!) disappear from enemies' sight.
Chicken Claw - casts Chicken Form status that lasts 2 turns.
1 Memory
2 AP
6 turns cooldown
A powerful ability, provided that a target has no physical armor - it turns a target into a chicken that runs around aimlessly.

2 Memory
1 AP
2 SP
1 turn cooldown
Another situational ability - it can heal your mortally wounded allies but you won't use it in most of your battles.

2 Memory
1 AP
1 SP
5 turns cooldown
This ability is useful when you must fight with an enemy that deals a lot of Fire damage.

Flay Skin - destroys a part of magic armor and lowers all of target's elemental resistance by a half, provided that it is not protected by magic armor.
1 Memory
3 AP
5 turns cooldown
If used right, it can greatly weaken a target - however, your target should lose all magic armor after using this ability.
Forced Exchange - exchanges Vitality percentage values of a caster and a target.
2 Memory
1 AP
2 SP
1 turn cooldown
A very situational ability, however, if you use it right, you can turn an extremely difficult fight into an easy battle. If your enemy has no physical armor then their Vitality percentage value will be swapped with a caster. For example - if a caster has 10% of health and your target has 90% then, after using the spell, your target has 10% and you get 90%. Thanks to this ability you can make your enemies lose thousands of health points.
Heart of Steel- regenerates physical armor each turn, the effect lasts 4 turns.

Unlocks Petrifying Visage ability.
Incompatible with Bull Horns ability.
1 Memory
2 AP
5 turns cooldown
Another situational ability that can alter a course of an entire battle. If a character is surrounded by enemies that don't have magic armor, they will become Petrified.
This ability also unlocks a spell, Petrifying Visage - it deals tremendous damage on a wide area and turns enemies into stone if they don't have magic armor.

Web creates a spider web on a surface which immobilizes everyone who steps on it.
Incompatible with Spread Your Wings ability.

Fly allows characters to reach areas that are unavailable on foot.

One of the best abilities in the entire game. Your character can fly each turn and becomes invulnerable to surface effects - they can't trip on ice, oil won't slow them down and fire won't damage them.
This ability is useful to all characters.
Summon Oily Blob - summon a creature that deals Earth-based damage and leaves Oil everywhere.
1 Memory
2 AP
6 turns cooldown
This spell is useful when you need Oil - this creature can create a lot of it. Otherwise, there is no point in using it.
Tentacle Lash - deals damage at a medium distance and inflicts Atrophy on a target.
Enemies with Antrophy status effect can't use their weapons and abilities that are connected to them.
1 Memory
2 AP
3 turns cooldown
One of the best abilities from this school, especially when it is used by a character that has a lot of Strength - it can deal a lot of damage.
Atrophy excludes most of enemies from a fight for 1 turn.
Terrain Transmutation - swap places of two different surfaces.
1 Memory
1 AP
2 turns cooldown
A very situational but also a very effective spell. You can swap places of two surfaces - remove Necrofire that is under your character's feet (swap it with a "clean surface") and cast it right under your enemies. Low cost and short cooldown are this ability's strong points.
