Most of the customisation items for characters are locked away in the Krypt mode, which requires you to spend coins to open boxes that contain random items. The boxes with the better items are much more expensive than the others and drain resources quickly.

What's the quickest/most efficient way to grind for the coins required to open a bunch of chests for the best chance at getting the items you want?

Note: The in-game store lets you purchase specific items, but it's only about 5 at a time and they're on a rotation that takes many real-world hours to rotate. It's not a viable solution to the problem of getting the items you actually want.


Ahh yeah there's no way around the grind, they really wanted you to buy time krystals for convenience. One thing that does help is the tower Cache of Wealth, insanely difficult but it does reward 150k+ depending on how you do. There's also the dailys that you can hit for 30k a day and the weekly race to the top. The race is not guaranteed gold but placing in the top 99% usually hands out 50k there. After that, the only way to maximize is to learn some long combos, as those contribute to your gold immediately and post-game.

Or, if you don't care about playing, just send your AI through some towers while you watch/play something else (you only have to hit x). It's bad, but most of the chests in the krypt don't go over 15k. Also, nobody plays Mortal Kombat here, if you find another forum please let me know.
