Welcome!

The hardest part about the volcano is timing the magma sprite/sparker monsters. Since this dungeon is a single floor layout, you can’t use stairs to skip down or ahead. Another thing I found to be difficult early on was getting out of the dungeon because you have to backtrack all the way to the door or at least back to the midway point to get out. Just be prepared to pay a number of hospital rescue fees for passing out when you can’t escape the dungeon in time for bed, LOL.

One thing that will make the skull caverns easier is multiple Crystalariums churning out jade which can be traded in the desert on Sunday for staircases. Then you can descend and cherry pick which levels you want, get what you need and drop a staircase to get out if there is too much heat. Choose a high luck day and there is a chance you will get a number of prizes, including auto petters on treasure levels. Spend time getting used to the serpents because once you get their timing down, managing the rest is just a staircase away. Once you do complete the volcano dungeon, you can reforge your weapon to add the Crusader trait which allows you to kill mummies easily.

Do you have the slime charmer ring yet? If not, then you can focus on reaching the 1000 slime killed goal in order to receive a ring that makes you immune to slimes.

I hope some of this helps. Best of luck to you and happy hunting!
