Upon imbibing this potion, you take on the appearance of a specific type of creature for 2d12 hours. The type of creature is determined when the potion is created. For example, you might have a potion of elf disguise or potion of frog disguise. Drinking the potion doesn't impart the knowledge of how long the effect lasts; the GM rolls the duration in secret.
The disguise doesn't change your traits or statistics, nor does it give you any of the special abilities of the creature you're imitating. It might affect what items you can hold or wear (for example, your new form might lack opposable thumbs). The potion shrinks you down to a minimum of size Tiny, the potion increases your size if the creature is larger than you, to a maximum of Large, or maintains your size if the creature is larger than Large. This does not change any of your statistics, with the exception of reducing your reach to 0 as a Tiny creature. The creature has to be of a specific kind, such as "leopard" or "lion" rather than just "cat", or "fire giant" or "ogre" rather than just "giant", but the potion can't cause you to mimic a specific individual creature.
The effects of this potion use the same rules as the Impersonate activity of Deception. Onlookers always assume you're the chosen type of creature unless they're actively Seeking. You gain a +4 status bonus to your Deception DC against such Perception checks and add your level even if untrained.
While drinking a greater potion of disguise, if you picture the specific form you want to transform into, the potion will change you into that form. You can attempt to Impersonate a specific individual, though you still need to roll Deception.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
ConsumableAn item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
PolymorphThese effects transform the target into a new form. A target can't be under the effect of more than one polymorph effect at a time. If it comes under the effect of a second polymorph effect, the second polymorph effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes specifically granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature, but rather just a generic creature of a general type or ancestry. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items.
PotionA potion is a magical liquid activated when you drink it.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
