what the heck is this

[Pocus]

really good play balance it seems. The higher you reach in a single field, the higher is the bonus, with some new effects appearing. On the other hand, as you show us, having several paths lead to several and differing advantages. This is where the studying of what you really want to do in your game is very important, before actually playing.

This recall me of old mom (Master of Magic) where you would spend hours (well at least me) thinking hard before playing, to try to arrange combos, like having rapidly the magic which transformed your troops into brutes with the right enchantments cast early.
