Shapeshift

Time: Quick Action Target: Self
Effect: Buff

Flavor: Choose one creature from the Creature List that has the Trivial or Easy Creature Tag. If the creature has Upgrades, also choose one Upgrade. If the Upgrade grants a choice of Abilities, choose those Abilities now. When you transform, you can optionally apply the Upgrade.

While you have this Ability you also have the "Shapeshifter" Creature Tag, giving you a Weakness to silver.

When this Ability takes effect, you gain 2 Persistent Stacks of Polyformed. As a Quick Action, you can clear all Stacks of Polyformed gained from this Ability, returning to your original form.

For reference:

Polyformed

Before reaching 2 Stacks of this Condition, there is no effect.
Once you reach 2 Stacks, you transform into a new creature as determined by the source of the last Stack of this Condition. Once transformed, you will remain transformed until you lose all Stacks of this Condition.

While transformed:

You must use your new form's Creature Sheet as your Character Sheet (replacing all your Stats, Skills, Abilities, etc.) with exception of the following:
- Keep your Shield, Health, and Vitality.
- Lose one Fleeting Stack from each of your Status Conditions. Lose all Stacks of Concentration. This effect happens again each time you take a new form or return to your original form.
- Keep your Social Stats and Social Abilities (but not your Social Skills.)
- Keep your mental faculties, though you will feel a subtle draw toward the creature's natural behaviors, including desires and fears.
Whenever you take Damage, reduce the Damage by 1 before applying your Defenses. You will then perform a Test using your Health as the Modifier (even if you reduced the Damage to 0.) If you Pass the Test, you remain transformed. If you Fail, you lose 1 Stack of Polyformed and can choose to lose a second. If you have 7 or more Health, you can choose to automatically Pass the Test.

Upgrades:

Copying.
- When transforming, you can match the exact look of any creature matching your Flavor(s).
- When transforming, you can touch a creature to transform into that creature with the following stipulations:
  - You gain one Upgrade of that creature. If the target is instead an Adventurer, you can gain one of their Trait Abilities instead.
  - If the target creature is Moderate, your Stacks of Polyformed are Fleeting instead of Persistent. When losing 1 Stack of Polyformed, you can use a Reaction to keep it.
  - If the target creature is Hard, your Stacks of Polyformed are Fleeting instead of Persistent (and you cannot keep them with a Reaction.)
  - When transforming into a Moderate or Hard creature, you can choose to take on their exact look while not gaining their capabilities. To do so, you must be able to chooses an Trivial or Easy creature that matches the target creature's Size and form. You will then use that Creature Sheet instead. For example, you could use the Commoner Creature Sheet when transforming into a human Arch Wizard.
Expanded.
- Gain both of the following or one of the following twice:
  - Gain another Flavor with an Upgrade.
  - Gain another Upgrade for an existing Flavor.
- Note: Each time you transform, you can still only choose one Creature Sheet with up to one Upgrade.
Partial.
- When transforming you can, optionally:
  - Keep your Language Skills and the Modifier of one Exploration Skill.
  - Keep up to three Abilities of your choice.
  - Apply one Upgrade from any of your chosen Shapeshift Flavors, regardless of your actual form.
- Note: When partially transforming to retain Abilities, Skills or to gain creature Upgrades, if your choice would require noticeable physical alterations, you may not fully pass as a genuine instance of that creature. For example, if you keep your Natural Weapons Trait Ability, keeping your claws might make you look like a monstrous Horse with claws.
- You can choose to not transform, gaining one Stack of Polyformed instead of two. When you do you can:
  - Set one Exploration Skill Modifier to that of your chosen Flavor.
  - Gain an Ability or creature Upgrade from your chosen Flavor.
  - Gain a Movement Style from your chosen Flavor.
  - Gain Natural Weapons, provided your chosen Flavor(s) would have them. (You gain no Upgrades for Natural Weapons.)
Powerful.
- Choose a previous Flavor choice to lose.
- Gain a Flavor. You can choose a Moderate creature instead of a Trivial or Easy creature. You can still choose one Upgrade from your chosen Moderate creature.
- When transforming into the Moderate creature:
  - Your Stacks of Polyformed are Fleeting instead of Persistent.
Swarm.
- If a chosen creature Flavors has the Swarm tag, you can now transform into Swarm of that creature. While transformed:
  - You count as a Massive(8u) Swarm while at 2 Stacks of Polyformed and a Huge(4u) Swarm wile at 1 Stack of Polyformed.
  - You have a Resistance to all Solid Damage.
  - You have a Weakness to all Damage from a Shape covering at least half your Swarm area.
Versatile.
- You can turn into any valid Flavor that you did not choose. You gain no Upgrades for the chosen form, but can still approximate any look as if you did have those Upgrades. For example, you could transform into a Bird and look like an owl without the "Sneaky" Upgrade that recommended for owls.
