Silicone Skin
This mutation adds the following soaks: 2-4 acid, 2-6 laser, 2-6 explode, 2-4 electric. In addition you become unhackable and ungibbable. However, Trauma kits become 20% less effective.
Incompatible with Zombie.
Usage
The soaks themselves are useful in very specific instances (for example flash whips). However, the real benefit to this Mutation comes from its secondary effect.
Being ungibbabable means your body will survive bombs, huge falls and train collisions entirely intact, and being unhackable means no one can cut implants or body parts from you.
This makes this mutation very useful for protecting your expensive implants - keep in mind that while other players can't cut implants from you, they can still drag your corpse away and wait for it to rot.
Your implants also do not take damage if your corpse rots.
