The Blue Crystal (4)
[Weapons]
[Armors]
[Your Current Balance: 5 Kill Points (KP)]
...
Three were only two options to be chosen from, together with Jeremy's current balance in the third line.
It appeared that Jeremy had five Kill Points, aka KP, from killing five kenkus. That simply meant he would get one point for every kenku killed.
Regarding the usage of those points, it was obviously for 'exchanging' items consisting of only weapons and armors.
Jeremy knew all too well why there were no Miscellaneous or Skills options within this second stage.
If the first stage was built to adjust newbies' mindsets and give them foundations in the forms of skills and mentality, then the second stage was the place where those tough newbies, who had managed to survive thus far, could enhance and upgrade their gears before going to live on Ortus.
