I do not recomend mining with jackhammer and explosive at same time, the explosion will completly ruin the layers of blocks and just make holes that nerfing a lot the what i recomend is:
- max jackhammer
- max treasure seeker
- max treasure hunter
- max token greed
- max lucky
- max speed
- max haste
- max nightvision
- (optional: key finder altho its pretty difficult to get it)
If enchants from your pick aint working check if u accidently toggled them or not before, keep in mind that low level of each enchant will do less effect and wont be that notable when mining so always max it out. Also you can prestige your pickaxe to get your pickaxe higher max level of enchants as for Prestige 0 pickaxes the max u can its level 1250, and for Prestige 1 is 2500 if i still remember right. The max you can get by prestiging is to level 5k ( this applies only for some enchants )
