You will probably need to "generate" battle cubes by spamming those energon recharges I'm sure you still have plenty of.

Since I just wanna get the exp to level up ASAP, I just cancel combat caches en "free" battles :P (otherwise it takes double the time to spend that energy, and I still have ~250 recharges from those first hits on bosses).

Otherwise, it is very possible that those 10 cubes won't be enough.
