• Rapid advancement increases the mutation's rank by 3.
• These three ranks don't count toward the rank 10 limit.
• Rapidly advanced mutations are still subject to the mutation rank cap that's based on character level.
• If you have 4 mutation points after gaining a level, you'll have a chance to buy a new mutation before you choose a mutation to rapidly advance.
• If you have no physical mutations at this point, nothing happens.

• Chimera still restricts the mutations you can acquire to physical-only.
• Whenever you buy a new mutation or mutate with Unstable Genome, one of the mutation options (chosen randomly but revealed to you) will have a rider effect: you'll grow a new body part.
  • The body part is chosen randomly from among all organic body parts and their variants.
    • head, blossom, cap, nuclear protrusion
    • face, antennae, feelers, sensory bud, sensory bulb, sensory nodule, sensory frill, sensory ganglion
    • arm, bine, branch, fibrous node, frond, leg, lobe, stalk, stem, taproot
    • bifurcation, fine root, leaf, pincer, pinnule, pseudopod, side hypha, tendril, tentacle, twig
    • feet, front legs, legs, rear legs
    • roots, lower hyphae, mulch
    • fin, dorsal fin, tail fin
  • The body part grows out of one of your existing body parts, weighted toward your body but any non-abstract body part is possible.
• If you have Irritable Genome and Chimera, when you buy a mutation, there's a 1/3rd chance you'll grow the new body part. This is in place of the augmented selection, since you Irritable Genome restricts your mutation choices. You will however get the augmented selections when Unstable Genome triggers.

OTHER UI CHANGES

MISCELLANEOUS & BUGFIXES

MODDING & DEBUG

• Appendage, a boolean flag for whether the body part type is an actual appendage (in addition to all previously existing requirements, this flag must be true for a body part to be dismemberable)
• UsuallyOn, which is used with appendages to designate the typical parent body part of this body part (for example, the UsuallyOn value for Face is Head, the UsuallyOn value for Hand is Arm)
• UsuallyOnVariant, which is used for body part type variants to designate a specific variant they're typically attached to (for example, the UsuallyOnVariant value for Sensor Array is Control Unit)
• ImpliedBy, which is used by body parts like Hands to designate that some number of another body part (in this case, Hand) implies their existence
• ImpliedPer, which works with ImpliedBy to specify how many of the implying parts are "satisfied" by the existence of this part
