Reptoid

Once per day, a reptoid can assume the appearance of a specific single Medium humanoid. The reptoid always takes this specific form when using this ability. The reptoid gains a +10 racial bonus to Disguise checks to appear as that type of humanoid. This ability otherwise functions as per disguise self, and lasts for 10 minutes × the reptoid’s character level. A reptoid can select a new humanoid form by spending 1 week preparing for the change, but can then no longer assume the previous form.

Reptoids receive a +2 racial bonus on saving throws against mind-affecting effects and poisons.

Reptoids are always considered to be armed when they are not using their change shape ability. They can deal 1d3 lethal slashing damage with unarmed strikes, and the attack does not count as archaic. Reptoids gain a unique weapon specialization with their natural weapons at 3rd level, allowing them to add 1.5 × their character level to their damage rolls for their natural weapons (instead of adding just their character level, as usual).
