Extra Arm
Source
Starfinder Enhanced pg. 43
You can rapidly grow an additional arm, although its existence is temporary, and it lacks the strength of your other limbs. As a move action, you can spend 1 MP to grow an additional arm. You can use this arm to hold and wield equipment and weapons of up to 1 Bulk in weight. This doesn’t increase the number of attacks you can make during combat. This arm remains for the duration of the combat, up to a maximum of 1 minute.
