So I guess it makes sense to upgrade the castle ASAP? To make the most of the exp boost it gives?
Seems to be going up in orb price though. Level three is 5 orbs, I thin level two was 3 orbs
Might be the best way to spend orbs in the game until limited-time banners come out.
I'm just blowing all my orbs on it. I'm thinking of it like a coin doubler.
