You can lean into this build if you encounter an early Elvish Orb.

Get the spear starred up asap, using the spear printing book can help.

You want at least 7 multi on the spear, ideally 10 (cap).

Speed the spear up with a Dream Catcher, don't forget to transition your Elvish Orb to your book for more juicy damage upgrades to your spear.

For the final encounter, the +80% crit is strong, also consider the 2 star to 3 star encounter if you're looking at going for a few more days.
