Sadly, they didn't. Only the 'Throwing Wrists' had a follow up—'Throwing Elbows'.
It wasn't even a competition… Throwing was just too OP, and Ambrosia agreed with me.
I took the wrists gene, and the leveling up continued.
Next, I put a point in defense—another low attribute. So far, the defense genes were the lamest, but this could just be a consequence of bad luck.
〔For improving defense, you have a choice of next genes: 'Thick Skin I', 'Poisonous Flesh III', and 'Radiation Resistance I'.〕
〔Thick Skin I: reduces all physical damage taken by 10%.〕
〔Poisonous Flesh III: makes meat badly poisonous, even if the venom gland is disposed of.〕
〔Radiation Resistance I: increases tolerable radiation amount and decreases risks of radiation sickness by 20%.〕
