Mage/Dark Wizard Help me perfect goofy Fatal

So, I've been attempting to make the most ridiculous Fatal build, and I ended up with this:
https://hppeng-wynn.github.io/build...0006C100ncC10006C1006CC0z0z0+0+0+0+0-jVRxbzw2
WynnBuilder build:
> Cancer֎
> Libra
> Anxiolytic
> Phage Pins
> Prism
> Prism
> Succession
> Diamond Fusion Necklace
> Fatal [t6f6f6]

It has a really high mana regen (and with 1 tp mana cost + manastorm), and you should probably never run out of mana. There is the obvious problem that it's really hard to hit enemies with every teleport damage tick, but assuming you can and there is a group of mobs, (for kill streak), you should be able to get 120k+ possible teleport damage. It has decent EHP, (32k), because of Cancer, but you could even take out Phage Pins and sub in Steamjet Walkers or something and be fine generally. This build has really high general skill points (double prism+diamond fusion is insane), but I think it makes up for it in damage potential and mana regen.

If someone who has more experience with higher level combat could help me make this build more viable, that would be really cool.

EDIT 1: This build also includes quite a few items that aren't roll dependent (and Phage Pins is easy to get a good one)

 

me when no one replies:

 

I think people gave up giving opinion on this when you said dps relying on tp spam and having boost based on killstreak (in short, very situational build)

 

Still, I'll try to point out stuffs as much as I can..

If you're willing to spam single spell, especially 2nd spell, it's better use raw cost instead of % cost.
If you have -100% or less spell cost stat then of course you'd have 1 spell cost. However, % cost can't protect you fully from the penalty ; Increasing next spell cost by +5. If you spam teleport in this case, you'll get -1 -> -1 -> -6 -> -11 -> -15 -> ... and more costs

However, raw cost can affect the spell cost penalty, letting you to spam even more.

An example build using raw cost

You're right.. you won't run out of mana easily. But the question is, is it worth it?
If you have a lot of mana and if you're unable to use those... then it'd be the waste.
It would be ideal to keep mana not more than you really need. And from replacing those mana items, you'll be able to invest on other stats you want ; Damage, walk speed, skill points, ehp, etc.

You have very low 2nd spell cost and you also have manastorm. So you should be able to replace a lot of those mana stuffs. You may not need Anxiolytic at all.

Any thunder build can apply thunder powder to their armor... this is not the stuff you can flex as the feature on this build.
Also, way too situational. Wynncraft presents various combat situations, and you're not just keep fighting against the crowd. For the single bossfight situation, especially on raid... you won't be able to abuse killstreak much. Don't rely on this boost for damage.

Rainbow slap
Not too wrong, but you barely have any other damage boost ids except str/dex. Considering most dps builds have str/dex... you won't be able to reach their damage with just str/dex. Even if skill point is the important matter in build, stay focused on stats you really need, like don't waste ring slot to random stuffs like Prism.

Now let's talk about the build concept in general...
From one of the patches, they added cps cap on casting spells. Which means you won't be able to spam in rapid speed as your expectation. This is pretty serious nerf against tp spam, thus unless you're willing to try off-meta, experimental meme build, I recommend you to make 'sane build'.

 

tysm for the comments
ik tp riftwalker isn’t really viable, this is just a (as you said) “experimental meme build”.
(and by the skill point thing i just meant that i needed to skill point spam to get the reqs

 

This has too much ehp

Also I’m pretty sure this does less dps than morph but I cba to check, and spell cost reduction is usually much more effective than mr
