Don't be ashamed and share us how much real money (nutaku gold) you have spent in this game (if any)

I think it's a fascinating topic because i see people who at the very least have spent 300 USD judging from their 6* helper squads (or maybe they are unrealistically lucky?)

Me personally i have been tempted to spend real money but yeah the prices don't seem tempting enough for me so i haven't had spent any money in this game, and i don't think i will unless it gets cheap and tempting enough.


Have you spent money in this game?
Was it worth it?
