Maybe I'm just missing something, but what is the damage for the strike? While it says "a special unarmed strike that deals lethal damage, lacks the archaic trait, and has an item level equal to your nanocyte level" there is no actual damage amount listed and in the CRB there is only one unarmed strike listed, not different ones by level. If it doesn't change the 1d3 damage listed in the CRB this isn't exactly a competitive option. It would basically force you to take IUS and even then it's still not really competitive. I feel like it could be a decent last resort backup weapon, but that's it.
