Honestly, watch some of DunkOrSlam's wand building videos and learn how to escape the holy mountain without breaking it (and then return).
Those two skills will help you build better wands for more survivability.
After that, I'd say just focus on learning the various levels and what kinds of enemies you'll be facing (and how to avoid them).
But, I'd try to avoid full spoilers of everything you can do until you beat the tutorial (or the final boss) ๐
