Min/Max Boards

seeing through a transmutation effect such as Polymorph requires divining information not available to the normal senses, since with a transmutation the subject is physically changed, not merely covered by an illusion. Mind Blank blocks such divinations.

Illusions such as Change Self and Invisibility work by placing a magically fabricated image over top of the subject. True Seeing sees through such magical fabrications. In this case, it is piercing a magical effect, not divining information directly.

Lesser Polymorph
Transmutation

Level: Brd 2, Sor/Wiz 2
Components: V, S
Casting Time: 1 standard action
Range: Touch
Target: Willing living creature touched
Duration: 10 min./level (D)
Saving Throw: None
Spell Resistance: No

You assume the form of a creature of the same type as your normal form, or of a humanoid or monstrous humanoid. The new form must be no more than one size category larger than your normal size. The maximum HD of an assumed form is equal to your caster level, to a maximum of 5 HD at 5th level. You can change into a member of your own kind or even into yourself.

Your class and level, hit points, alignment, base attack bonus, ability scores, and base save bonuses all remain the same. You retain all supernatural and spell-like special attacks and qualities of your normal form, except for those requiring a body part that the new form does not have (such as a mouth for a breath weapon or eyes for a gaze attack).
You keep all extraordinary special attacks and qualities, except those that rely on gross physical characteristics that your new form does not have (wings, claws, etc).
If the new form is capable of speech, you can communicate normally. You retain any spellcasting ability you had in your original form, but the new form must be able to speak intelligibly (that is, speak a language) to use verbal components and must have limbs capable of fine manipulation to use somatic or material components.

You acquire the physical qualities of the new form while retaining your own mind. Physical qualities include natural size, mundane movement capabilities (climbing, walking, and swimming only, to a maximum base speed of 60 feet for all movement modes), natural armor bonus (up to 1/2 the caster level, or 5, whichever is less), natural weapons (such as claws, bite, and so on), and any gross physical qualities (presence or absence of wings, number of extremities, and so forth).

A body with extra limbs or natural weapons does not allow you to make more attacks (or more advantageous two-weapon attacks) than normal, regardless of what your assumed form's normal attack routine is. For example, if you normally only have one attack, then you can choose one of your new form's natural weapons to make that attack with, and that is the only attack that you get. If you normally fight with two weapons and your new form has two claws and a bite, then you could use your bite for your main-hand attacks and one of your claws for your off-hand attacks. You'd still only get the same number of overall attacks that you normally have, however, and at the same bonuses (not counting bonuses or penalties due to size change, etc).

You do not gain any extraordinary special attacks or special qualities not noted above under physical qualities, such as darkvision, low-light vision, blindsense, blindsight, fast healing, regeneration, scent, and so forth.

You do not gain any supernatural special attacks, special qualities, or spell-like abilities of the new form. Your creature type and subtype (if any) remain the same, regardless of your new form.

You can freely designate the new form’s minor physical qualities (such as hair color, hair texture, and skin color) within the normal ranges for a creature of that kind. The new form’s significant physical qualities (such as height, weight, and gender) are also under your control, but they must fall within the norms for the new form’s kind. You are effectively disguised as an average member of the new form’s race. If you use this spell to create a disguise, you get a +10 bonus on your Disguise check.

When the change occurs, your equipment, if any, either remains worn or held by the new form (if it is capable of wearing or holding the item), or melds into the new form and becomes nonfunctional. Magical items that are capable of resizing to fit their user will do so to accomodate your new form. When you revert to your true form, any objects previously melded into the new form reappear in the same location on your body they previously occupied and are once again functional. Any new items you wore in the assumed form and can’t wear in your normal form fall off and land at your feet; any that you could wear in either form or carry in a body part common to both forms at the time of reversion are still held in the same way. Any part of the body or piece of equipment that is separated from the whole reverts to its true form.

Polymorph
Transmutation

Level: Sor/Wiz 4
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: Willing living creature touched
Duration: 10 min./level (D)
Saving Throw: None
Spell Resistance: No

This spell functions like Lesser Polymorph, except as noted here. The new form may be of the same type as the subject or any of the following types: aberration, animal, dragon, fey, giant, humanoid, magical beast, monstrous humanoid, ooze, plant, or vermin. The assumed form can’t have more Hit Dice than your caster level (or the subject’s HD, whichever is lower), to a maximum of 15 HD at 15th level. You can’t cause a subject to assume a form more than two sizes larger than its normal form, nor can you cause a subject to assume an incorporeal or gaseous form. The subject’s creature type and subtype (if any) do not change. If slain, the subject reverts to its original form, though it remains dead.

The subject loses its own racial bonuses to Strength, Dexterity, and Constitution scores, and Natural Armor. It gains the racial bonuses of the new form for these (up to 1/2 the caster level or 10, whichever is less). The subject retains its own Intelligence, Wisdom, and Charisma scores. If the subject does not have an ability score, then it does not gain one from this spell, and vice versa. Regardless of any changes to Constitution due to this spell, the subjects hit points do not change.

Incorporeal or gaseous creatures are immune to being polymorphed, and a creature with the shapechanger subtype can revert to its natural form as a standard action. Unlike Lesser Polymorph, this spell can grant the ability to fly with wings and/or burrow.

Material Component
An empty cocoon.

Greater Polymorph
Transmutation

Level: Animal 8, Drd 8, Sor/Wiz 8
Components: V, S, F
Casting Time: 1 standard action
Range: Touch
Target: Willing living creature touched
Duration: 10 min./level (D)
Saving Throw: None
Spell Resistance: No

This spell functions like polymorph, except as noted here. It enables the subject to assume the form of any single nonunique creature (of any type) from Fine to Colossal size. The assumed form cannot have more than your caster level in Hit Dice, or more hit dice than the subject. Unlike polymorph, this spell allows incorporeal or gaseous forms to be assumed.
The subject loses its own racial bonuses to Strength, Dexterity, and Constitution scores, and Natural Armor. It gains the racial bonuses of the new form for these (up to the caster level). The subject retains its own Intelligence, Wisdom, and Charisma scores. If the subject does not have an ability score, then it does not gain one from this spell, and vice versa.

You can become anything you are familiar with. You can change form once each round as a free action. The change takes place either immediately before your regular action or immediately after it, but not during the action. If you use this spell to create a disguise, you get a +10 bonus on your Disguise check. Parts of your body or pieces of equipment that are separated from you do not revert to their original forms until the spell ends.

Focus: A jade circlet worth no less than 1,500 gp, which is placed on the subject's head when the spell is cast. (The focus melds into the subject's new form when it changes shape.)

Change Enlarge Person to Enlarge Creature, and drop all restrictions on creature type, and stacking with other magical affects that increase size.

Polymorph Any Object and Shapechange no longer exist.
