Mage/Dark Wizard Cascade Build For 1.20

I've been polishing this cascade rainbow mage build a lot recently, and it's currently at a point where I am very happy with it: https://wynndata.tk/s/q3c2vf - necklace is named Recalcitrance

(although it says too many skill points used, these are the skill points I get with my loadout)

It has low mana regen/steal, but makes up for it with very high DPS to fill in while spamming the 19k meteors. It's a bit squishy, but I think it's really good for having no mythics and is quite budget friendly. It's a glass cannon mage build, over a tanky one, since mage spell spam is op

anyways, let me know what you guys think and what improvements could be made :)

 

Rainbow fast hybrid huh :)

Here's your build in WynnBuilder: https://wynnbuilder.github.io/#3_0cD0U209U0Fp0Fx0Fx0TN0uH07f0t0k0k0k0s1g000010036C (not sure how you're wearing this in-game tbh)
Meteor damage is good, but the high spellcosts and low mana sustain combined make for low viability of spells.

My attempt: https://wynnbuilder.github.io/#3_0Uk0Pf09U0k50WA0Jf0TN0OH07f0j0n1U0e0r1g000010036C
Melee damage is comparable, and Meteors are 2k lower. But, Meteor cost is now 2 mana instead of 5, and there's more mana sustain, so spells can be used more often.
