I have like 105k atm. Granted I've bought all the weapons and gear as they appear in the shop. I'm also going through and wearing everything to unlock abilities so I usually spend some to open more slots.
I always spend them all on gear upgrades (guess i already mentioned that before) but I already fully upgraded most of the gear and I think I'm only missing about 2 pieces. WE NEED MORE GEAR T_T
Around 270,000. I had more but then I rerolled some clothes and then got tired since I kept getting trash abilities. (Special Duration Up doesn't help when everything you use has Inkstrike. )
I've got ~ 530k, and I believe Ive bought out everything the shops can offer now. I still have about 15 sea snails too, so I doubt this ammount will go down until the new gear next month.
Okay I'm at 600k now. I'm hoping to spend it all on the new head or weapons and it should leave me with enough to have a few increased slots on my gear. Hopefully I can get some good gear that looks fresh too!
