Is there a good way of upgrading Ur pick levels other than mining?
Use explosive enchant until your pickaxe is level 10.
Once u get Level 10 pickaxe, bu right clicking your pickaxe press the button u showed " Prestige pickaxe " and obtaine Prestige 1 on your pickaxe.
When your pickaxe is Pickaxe Prestige 1 (PP1), Max your Jackhammer enchant to level 1000 ( max for PP1 ) , and right click your pickaxe, on the bottom left there is button *disable enchants* and disable Explosive enchant. From now on just run and grind blocks while Jackhammer keeps procking and this upgrades your pickaxe really fast.
For extra speed i suggest u get Jackhammer gems. U can find those gem boxes while mining and getting specific raw block numbers. Other option to get those gem boxes is to open /expshop, and buying those gem boxes with exp. -- EXP shouldn't be a problem, as doing /quests u will get pretty high chance of getting big amounts of EXP.
For additional boost i suggest u go grind Soul gems in Soul cave and use those soul gems to upgrade pickaxe enchant "Soul Luck" whitch gives u a massive boost on procking pickaxe enchants.
If u got more questions let me know down below, will try to answer (if any) as fast as possible. Happy mining
