So right now my guardian is the deepest guardian in the league. Not that i'm super deep, but it means people have seen me and are asking questions. I thought I'd just answer what I can here because this build, although a pretty quick mapper, isn't a "mapper" like you would expect blade vortex + herald scaling.

The core concept is getting the 3 auras from the new guardian ascendancy. Use the mana you would usually reserve for auras with heralds. Now use a physical spell and convert it through to fire via call of the brotherhoods. You are now getting the full benefit of all 3 auras and all 4 heralds. hatred and wrath give something like 40% more damage each anger is ~10% and then the heralds do like 40% more -15% more depending on which one.

I also turn every int travel node into +4 stats until I can do the 155 dex for blade vortex and 155 strength for determination, then every single int node left I do 5% herald effect which is ~2% more damage each travel node.

Basically, I built this build with the defenses before the offenses. It's very tanky, it was designed to be. I'm scaling herald effectiveness as much as possible and running 4 heralds along with 90 max res and a nebulis. It still has pretty good damage, but I don't want people to assume it's some 20 million dps thing.

Here are a few videos.

T16 strand with a deli mirror and I do all the essences. That is my farming strategy btw, I get sulphite speccing all the delve, essences, and delirium nodes. As you can see the damage isn't overwhelming, but I also am never in danger of dying.

This build was built to farm delve. Here it is doing a harbinger node with some pretty nasty stuff at around depth 600. Harbinger is maybe the hardest type of node in delve. Either that or beyond. I am only in danger when I can't get away from a mana siphoner for a couple of seconds. Luckily aegis did some work.

I'm now going to finish farming my mageblood so I'm done with upgrades for awhile. If you have any questions feel free to reach out.
