Yeah, I should’ve phrased it differently. I meant the best way to 200 using a mix of treasures balanced a bit for what we actually get from chaos portals. A calculation like this is what I was thinking. Probably wouldn’t be too hard to figure, if the spreadsheet went beyond 9 rows (probably doable, but will take some work).
EDIT: To your point, you’re trying to solve the problem of getting to level 200 in a single month; but if players can get away with going only to 100 in some factions, they can use the extra treasure to reduce their cost of going to 200 in other factions. I’m wondering the best way to optimize spending of that extra treasure.
