I generally take the standard route until about the jungle or so. I keep my eyes open for wands+spells able to dig through holy mountains, teleport wands, and wands capable of bringing down bosses like Squidward and others. If I find them, I jump the rails and go do other things, if not I focus on just beating Kolmi. I generally can take the first option 1 time out of every 5-6 tries, though I am sure I could do it more often if I was better!
