You have adapted to your mutation and can make use of it to a more effective degree.
Prerequisite: One minor or major mutation.
Benefit: Select one of your mutations that deals damage. The number of damage dice dealt by that mutation increases by one. So, if you have a mutation that normally deals 1d4 points of damage, that mutation now deals 2d4 points of damage.
Special: You may take this feat multiple times; each time it applies to a different mutation.
