Mage/Dark Wizard Help Ice Snake focused builds?

i tried ice snake mage in 2.0 but my real damage was low.
mana was not bad, DPS on housing dummy was fine(carried from 30 winded timelock) but actual boss dps was low.
how can i improve my gaia spellspam?

current ability tree:
https://hppeng-wynn.github.io/build...c40c90Qa22111111111g00001006C6zz++++-VU+ovxT0

other requirements
- no other mythics (too poor for other mythics)
- no ophanims(i dont like it) or arcane transfer without over super high ls and ehp(skillissue)

 

I'm not that great at making builds but if you're focusing on Ice Snake it would be extremely beneficial to get Snake Nest (3>1 so more damage). I would swap out Mana storm because honestly it's not gonna make that much of a difference as long as you have enough mana sustain via mana steal and/or mana regen (regarding that build, as long as you cycle between Heal, Teleport and Ice Snake you should be fine)

 

tbh, a snake focused build is not worth it, you can get much better dps with meteor (or tp from warp)
