For a more in-depth description, see my other build: Farming Frags Fast. This is an option if you have Guardan and Hermit but not Warden.
However many LTs vs Owls you use is up to you. I haven't experiemented much, but will once she's live (posting this now so I have some Guardian builds up early). I'd still recommend some DSTs facing south to pick off mobs. But again, I haven't experiemented.
Empowering Shrine makes the Cupids SO much easier, especially as a DPS Huntress. 1.4-1.5x Damage is just that good, and helps even more if your Huntress is bad, like mine still is.
Nature Pylons are great with Owls, since they resistance Pylon gives is the same type as Squire Guardian, which increases their damage. Of course, they still provide range, which helps a bunch.
