Physical Mutations

MUTATIONS AND ARMOR

Physical mutations have a few limitations.  If the mutation is a bioweapon or has a Disguise DC modifier of +5 or more, you can only use it while wearing armor that has been custom crafted for your unique physiology.  The exception to this rule would be the any of the nano-armor present in the Gravity Age: Nanotech Emporium.  

Mutations with armor restrictions will have one of the following five descriptions;

• “You are limited to wearing custom armor or nano-armor with this mutation.”
• “You are limited to wearing nano-armor with this mutation.”
• “You are limited to wearing light armor, or any nano-armor with this mutation.”
• “You are limited to wearing custom light armor or light nano-armor with this mutation.”

BREATH WEAPONS & BITE ATTACKS

Breath weapons and bite attacks cannot be used in the vacuum of space without disengaging the environmental protection a suite of armor gifts to its wearer.  Under these circumstances using a breath weapon would expose the character to the void and decompression would begin.  For additional information on space and decompression, see the "Environment" section in Chapter 11 of the Starfinder Core Rulebook.
