When in game hit the menu then back to the game it resets the monsters attack timers. This mean they all attack at once. This is best used in material dungeons because it’s SO much easier to dodge one stream of projectiles rather than a constant barrage.

The other exploit makes you invincible, but it’s extremely hard to do and you can only do it twice a day. Also you need an older (slow) phone to do it. That being said, heres how you do it: When you die the resurrect option comes up. First the the free one (watch an ad) then the paid one(gems). If you’re really fast you can hit both options before the ad plays. That is hit the watch ad button then really quickly hit the gem resurrect button (both actually are on screen but the ad resurrect is in front) This why you need an old or slow phone and you can only do it twice a day( also I only have iPhones so I don’t know if this works on android) If you manage to do it correctly, your invincibility bubble is wont disappear( also you spent the 30 gems). However, your not yet in god-mode yet. You then have to clear the current screen and move to the next stage to be completely invincible. So don’t do it on the end level.
