I had an idea to improve the game, which would be to create a super treasure vip cave, which would see a lot more jewels (for example 10-20), which would see a lot more elemental cells, which would see a lot of food (500,000), which at level 30 you gain a mutant rune level 10, at level 60 you gain cells from some nemesis monster, and at level 90 comes an elite monster 5 stars
but only those who have the premium pass could enter this second treasure cave, this would encourage people to put the premium pass, as it would be a much better advantage
