Just a suggestion

Seeing as I am Lewis I recommend you make me a mod and I will take some form of canon hero eventually

I planned on it lol

How are you leveling up grids, i woulda said that in each level you want to up it goes as follows

1-2 = 10 XP
breaching a boundary but not a huge one
2-3 = 13 XP
3-4 = 15 XP
much bigger gap to breach such as superpower versions
4-5 = 20 XP
to get to the best you need to have a lot of XP
5-6 = 25 XP
