Blood platelets evolve to clot far faster, increasing endurance and reducing bleeding from wounds.
Superclot gives the following effects:
+2 to Endurance Immunity to the bleeding status effect
Cannot die from bleeding, slight boost to Endurance-based skills. Great alternative to bleeder for brainy characters, as the extra endurance helps with drug-taking and fighting for long periods of time. If you'd rather use focus abilities while fighting, this is the better choice, and the endurance bonus makes it better for many spear users as well.
Incompatible with the bleeder mutation, which means no frenzy-on-command.
