Schemed Against
After much extraction, Ed managed to find the following unique skills inside Bloody.
'Blood integration is probably the unique skill that allowed it to get so huge' The blood clot must have found lots of enemies on its path to the exit. How the enemies contained so much blood was a separate thing, however.
'It must have learned fragment as a result of blood integration' That was the only explanation for the low-level of the skill Ed could find anyway. It did make sense though so he didn't think about it too much.
As for how it could kill these creatures… Some skills on Bloody had leveled up quite a bit in the short while… eye spy lvl 3, metal body lvl 4, charge lvl 3, poison body lvl 5, and slither lvl 6.
