Extra Arms

The character grows an additional pair of arms. The extra arms look and behave exactly like the character's other arms.
Type: Major positive.
Effect: As a creature with more than two arms, the character gains a +4 mutation bonus on Climb checks and grapple checks. If the character also has the Claws mutation, these arms have claws too. For purposes of combat, the extra arms count as secondary natural attacks, and thus suffer a -5 penalty to attack rolls when making a full attack with all four arms. While these arms can hold and wield weapons, the character cannot attack with more than two weapons at a time unless they have some other ability that allows them to do so. Fighting with two weapons carries the normal penalties.
The extra arms do not provide any extra strength or carrying capacity, though at the GM's discretion, the character may be able to carry a slightly larger volume of equipment.
Biotech: Graft.
