Strategy

My strategy would be to keep grinding zones and scrap ingredients at Yes-man.

When you are at the unknown underworld zone i would keep staying as long as you could at each unknown monster to get as much ingredients to scrap for invention exp.

This would be the fastest way to get 99 invention.
