Cyanide escaped from the school building, his business done, and prepared to head back to his base at the Aterra Headquarters.
With the slaying of that Stage Three Mutant (presumably), he had gained two straight levels from 22 to 24, and put 10 of the CP he received into AGI while purchasing Inspect II with 1 SP he got so he could see other players' specific stat distributions. Because the base skill was a Core one and cost 0 SP, the upgraded version only cost 1. This left him with 10 CP left to spend and 1 SP, the former of which he spent on VIT since he was going for a more or less balanced stat distribution while conserving the 1 SP.
Why was he obtaining this [Inspect II] skill? Well, since other survivors were going to be starting to flock towards the city of Lumina, Cyanide needed to be ready. He always was.
