Mage/Dark Wizard How can I improve this build?

https://hppeng-wynn.github.io/build...0e+I1x16-Y1g000010009I0z0z0+0+0+0+0-VcFpfEdT0
WynnBuilder build:
> Aphotic
> Chef Hamsey's Apron
> Ophiuchus
> Gaea-Hewn Boots
> Diamond Hydro Ring
> Silver Hydro Ring
> Prognosticum
> Ominous Wind
> Nepta Floodbringer [w6w6]

conditions:No mythics

 

There's no saving that build. Try this one instead:

https://hppeng-wynn.github.io/build...f0n100s1P0n1g00001003FU0z0z0+0+0+0+0-tMpxjikE
WynnBuilder build:
> Cancer֎
> Libra
> Vaward
> Violet-Shift
> Ingress
> Ingress
> Succession
> Diamond Fusion Necklace
> Cascade [a6a6t6]

This one has much better damage and ehp than the one you posted. It has less mana regen, but still has much more than enough to sustain you. I also improved the tree to have winded, which drastically increases your dps. And your wand does have to be powdered that way, as full t6 air powders actually significantly decreases your damage. The one thing this build is worse than yours in, is that this build’s heals are quite a bit less effective, but still should be good enough to keep you going.

 

Here's a couple others I came up with:

https://hppeng-wynn.github.io/build...G-Y0j1T-Y161g00001000FU0z0z0+0+0+0+0-tMpxjikE
WynnBuilder build:
> Boreal-Patterned Crown
> Wanderlust
> Ornate Shadow Cover
> Skidbladnir
> Yang
> Cold Wave
> Lachesism
> Abrasion
> Nepta Floodbringer [a6a6]

This one still uses nepta floodbringer, if that's what you're really attached to. It's slightly glassier than your build, but has nearly double the damage with some really nice QOL stuff.

https://hppeng-wynn.github.io/build...n-Y1C15-Y161g00001007lU0z0z0+0+0+0+0-tMpxjikE
WynnBuilder build:
> Boreal-Patterned Crown
> Wanderlust
> Ornate Shadow Cover
> Skidbladnir
> Yang
> Cold Wave
> Lachesism
> Abrasion
> Predposledni [a6a6a6]

Same armor as above, but with a better wand. This wand upgrades the set in basically every way.

 

I'm not into rainbow because they're a jack of all trades, I like the third build because I like focusing in 2 element damage
