You will get banned when you push stages in excess of your current status, like gold or damage. For example, your normal gold is 900, your damage is 1000, and with those stats, your max stage can reach 1000, but if you use a mod and gain 9999 gold and 99999 damage with a max stage of 9999, then the system will scan your account and do some calculations to see if it's legal or not. If it finds anything abnormal, then it will tag your account as "Teapot." After 3 or 4 days, if Teapot doesn't disappear, then your account is permanently banned. So unlimited mana and no cooldown skills, fairy video skip, and VIP features are all safe. I've been using them from 1 to 130k stages with no Teapot
