[SC] Arcmage Arc Big-Zap Build

Video Example in T16: Arcmage Arc ft. Tryp+Marylene+Sandstorm Combo - YouTube

Hello! First, I apologize for this formatting, I'm not good at making reddit posts; hopefully you'll be able to get past that. This is a WIP and I show my current character (level 88), so it DOES work, but feel free to make your own edits. I'll probably come back and rework this post with a full build guide once I've achieved ~15mil dps. Anyway...

It's possible this has been posted before, but I wanted to give my two cents on this build archetype. Yes, there might be better builds out there with this combo, but I think the starter viability (assuming you have enough to get the 3 required uniques) makes this build insane. You can clear red maps after getting just those items at level 68 (you will obviously be very squishy at that point, though).

We'll be abusing the combo of Sandstorm Visage + Trypanon + Marylene's Fallacy. I also want to give credit to BehindEyesGaming who I first saw using this combo and Phoenix who heavily inspired this skill-tree.

These 3 items, together, will grant you a 100% crit-rate for spells and + 294% Crit Multi (Marylene's Fallacy's -40% less doesn't affect it, for some reason, where Controlled Destruction DOES actually reduce our crit-rate).

Pros:
0. Over 20mil damage for under 8~12 div investment

1. Instantly clear legions with your Vaal Arc
2. Long-range, insta-zaps sanctum monsters with minimal standstill (If you're using the Unleash variant)
3. Very high single-hit damage, great for hit and run bossing.
4. Enough regen to reliably run RF at all times

Cons:

1. DoTs really hurt us as it kills our mana regen, which is essentially Life Regen with Agnostic
2. Hard to get Chaos Resistance, which makes farming Chayula Breaches difficult
3. 3 Required uniques, which are currently cheap, but may not be in the future
4. Each purchase is a giant boost in DPS, so if you don't farm reliably, you may be stuck in a specific damage bracket for a while until you get those upgrades.

Concept:
This build revolves around the 3 items previously mentioned. You have 100% crit on your spells; so what do you do with it? Well, we get high added damage that we can scale from Archmage, then lots of crit multi (near 1000%+!), lots of pen, and finally cast speed/general damage. It's insane what we can achieve against even uber bosses (around 10-15mil at endgame with ~30 div investment).

Here's the PoB: https://pobb.in/70B67zLc-U5j

Disclaimer: I AM currently running this build on a character and can clear T16 maps with a legion/breach/deli/beyond tree. It's been great, but has lowish survivability without higher levels and Taste of Hate; especially since I have not optimized the build in-game at all. You can see my current character here: https://pobb.in/dpPZ6QOtepXB. I barely have any of the items or gems in my end-game build and my DPS is already 4mil; more than enough to clear T16 maps and legions.

The above said, this build is still a work in progress. Things are very unoptimized and I just kinda wanted to put this out there since I was looking for a build like this and couldn't find any reference using those uniques. I hope others can take this and make it even better.

Edit: Changed POB to have slightly less damage, but gave it 60% spell suppression, positive chaos res, and slightly easier to obtain jewels that gives ele-res. DPS is now 31mil, but it's much tankier.
