Charisma +2; Dexterity +1 OR Intelligence +1 (choose when creating the character)

You can speak, read, and write Common, Deep Speech, and one additional language of your choice.

As an action or bonus action, you can alter your form to that of any Medium, Small, or Large humanoid you have seen. This transformation is physical and biological, not magical.

You may change your appearance, body shape, voice, and perceived gender. Your equipment does not transform with you.

This transformation lasts until you change again or die.

While shapeshifted, you leave no tracks or scent unless you choose to. You emit no alignment or magical aura detectable by divination unless the effect bypasses nonmagical disguises.

You can cast the Detect Thoughts spell without components, using Charisma as your spellcasting ability. While Detect Thoughts is active, you have advantage on Charisma (Deception) and Charisma (Performance) checks made against the target, and you can instinctively mimic their emotional tone, vocal cadence, and mannerisms.

Spell save DC = 8 + your proficiency bonus + your Charisma modifier.

You maintain two fully developed alternate identities, each with its own appearance, voice, mannerisms, and background.

You can switch between your created identities as a bonus action.

While using one of your personas, you have advantage on Charisma (Deception) and Wisdom (Insight) checks made to impersonate, blend in socially, or adapt to that identity's expected behavior.

You can replace or reshape an identity during a long rest.

You have advantage on saving throws against being charmed, being frightened, and against divination effects that attempt to read your mind or compel truth.

You automatically succeed on saving throws against the Zone of Truth spell. You appear truthful unless a creature succeeds on an Insight check against your Deception check (minimum DC 20 before modifiers).

After observing or interacting with a humanoid for at least 1 minute, you may replicate one of the following traits until your next long rest:

• One language they know
• One tool proficiency they possess
• One simple or martial weapon proficiency they possess
• One behavioral trait (such as gait, gestures, tone, or posture), granting advantage on Deception checks made to impersonate them

You have a climbing speed of 30 feet and a burrowing speed of 20 feet. You can burrow through soft earth, sand, loose soil, or unworked stone. You do not leave a tunnel behind unless you choose to.

While burrowing, you can hold your breath for up to 10 minutes.

While using Perfect Shifting Form, you may suppress the following:

• Footprints
• Body scent
• Detectable alignment or aura
• Psychic signature detectable by telepathy or similar abilities

You cannot be detected by telepathy unless a creature is physically touching you.

You can telepathically speak to one creature at a time within 30 feet. The creature must understand at least one language. This communication requires no action and functions regardless of your current form.

You do not sleep. Instead, you enter a 4-hour trance, remaining semiconscious. You gain the full benefits of a long rest after this trance.

You have mastered the art of perfect infiltration.

• You may cast Alter Self at will, without components.
• You may use Perfect Shifting Form to assume Tiny or Huge humanoid shapes.
• Once per short rest, when you succeed on a Deception check while shapeshifted, you become invisible until the start of your next turn.
