A partir du niveau 1, vous avez un don pour imiter les humanoïdes que vous avez déjà rencontré. Dès lors que vous utilisez votre capacité de Changement de forme, vous pouvez choisir de vous transformer en une créature de type “Humanoïde” que vous avez déjà vu et dont le facteur de puissance n'excède pas le FP max définit par votre niveau.

Par exemple, au niveau 1, si votre personnage a déjà rencontré un Kobold, vous pouvez utiliser une charge de votre changement de forme afin de vous transformer en un kobold. Mais à ce même niveau, vous n'êtes pas encore capable de vous transformer en Gobelours étant donné qu'ils sont de FP 1 et qu'il vous faut être niveau 3 pour cela.

At 1st Level, You gain Proficiency in either the Deception or Stealth skill.

You can also channel your doppelganger heritage, As an action, you can polymorph into any humanoid of your size that you have seen, or back into your true form, However, your equipment does not change with you. If you die, you revert to your natural appearance.

At 10th level, You have become a master of inflration among the races with which you can ShapeShift into. You can mimic the speech of another person or the sounds made by other creatures.

You must have heard the person speaking of the creature make a sound, for at least a minute. A succsessful Wisdom (Insight) check contested by your Charisma (Deception) check allows a listener to determine if that effect is faked.

You also gain advantage on targets that haven't take a turn in iniative yet.

Starting at 10th level, your shape changers essense can influence your forms, making them stealthier. As a part of the bonus action used to Shapeshift, or as a bonus action whilst transformed you can choose to empower your form with the camoflauged skin of the doppelganger. The creature retains all of its statistics, except as noted below:

Senses: The creature gains darkvision out to 60ft. Shadowed Strikes: All Melee attacks of the creature deal an additional 1d4 Poison damage. Camoflauged Skin: The creature gains advantage on Dexterity (Stealth) checks made to hide and move steathily, as you skin gently shifts color to match your surroundings. Stalker: While in this form you are able to take the Hide action as a bonus action.

You are able to Shade-Shift once per long rest.

At 18th level, you are always under the effects of the Detect Thoughts Spell. Also as an action on your turn you can attempt to dig deep into a creatures mind and find the thing it fears most.

The target must make an Intelligence saving throw, on a failure you learn there deepest darkest fear, on a success you dont learned the deepest fear, and you are unable to use this ability on them until 24 hours has pasted. If a target is immune to the Frightened Condition or its mind is unable to be read (Such as with a Mind blank spell), they always succeed on the Wisdom Saving throw.

Once you know a creatures deepest fear, you can use your action on your turn while they can see you to transform into the thing they fear most. Shapeshifting in this manner does not expend a ShapeShift charge. The DM will select an appropriate creature. While the target can see you in this form they they become Frightened, they are able to make a saving throw at the end of there turns, if they cannotsee you. While they are frightened, any melee attack agains the target deals and additional 2d8 Psychic damage.

The Saving throw DC for both the Intelligence and the Wisdom Saving throws and the Detect thoughts spell is: 8 + Proficiency modifier + Your choice of your Charisma or Intelligence modifier.
