Archer/Hunter Lv 75 Boltslinger

Hi! I was wondering if there were a way to improve my current build
I cast a lot of spells

Here is what I am running (cannot post links b/c too few posts)
WynnBuilder build:
> Purified Helmet of the Legends
> Adamantite
> Crystal
> Sodeta Boots
> Photon
> Draoi Fair
> Vindicator
> Durum's Serenity
> Maelstrom []

Here's another thing that I had before
WynnBuilder build:
> Clearsight Spectacles
> Millennium
> Morph-Iron
> Morph-Gold
> Morph-Emerald
> Morph-Topaz
> Vindicator
> Morph-Ruby
> Maelstrom []

How should I improve upon these builds?
I'm using the very basic "haha funny" level up all boltslinger abilities and ball

 

I'd sa champion armor, it really is good

Prbly better than this but I am too lazy to type out your builds in wynnbuilder

________________________________

Damage is better with champion

________________________________

Health sustain is def better

 

High sp flexibility with champ and mana sustain is abt the same

Health abt the same

Ccl: get champ, trust me (I finished the game with it it's way too op)

this maybe? if you want more mana regen
your build is already good for lvl 75 though, gear isn't that important until around lvl 100
