Although Ed didn't know what skills all the mobs he previously met had, he could make some good guesses. How they moved was the simplest indicator.
For example, some had legs. If they had legs they had movement skills and if the legs they had allowed them to run fast they almost definitely had a good movement skill. While there were no guarantees, the possibility was high enough to bet on.
'But even without the high possibility…' Ed already have a couple of good ideas for what to use just from his known arsenal.
[Millipede (Corpse)]
The Millipede had an insane amount of legs so it passed the first check. Judging from his encounters with it the creature also had a unique skill to complement those many legs.
[<(Crawler) Thousand Legs lvl. 1> Skill Ink]
