GS Guardian is dum

So here's a GS guardian. Lots of Mana and ergo lots of ES.

So you're going to get at least 8 grand spectrums which give +15 mana per jewel. This means that per jewel you will receive 120 mana. With 8 this means 960 base mana.

From the tree we'll get something i nthe region of +700.5 max, with 129% increased (without say - pledge of hands, which you can use if you really want it doesnt matter).

With items (not necessarily adding max aside from uniques) this translates in to a 7034.8 Mana pool without too much trouble. So we reserve it.

This provides a base ES discipline of 1055.22 ES. Yes, 1055.22. Then when you put everything you end up with something in the region of 10199.9798 ES. I mean, you can go higher with your items... Without CI and without vaal disc. Turn on vaal disc, and we get 13604.9798. Turn on Vaal Disc with CI and we get 15645.72677.

If you swap to mirror tier gear in a couple of slots you end up with 123037198 without CI or vaal Disc, 15708.7198 with vaal disc and you end up with like 18065.02777 with CI and vaal disc.

So what you're going to do is turn on RF. Which is going to have a base damage of just over half your es. Like maxed out just over 9000 base damage. Then you can go and add all this other crap and maybe cast a spell. Who cares.

Or you can just play vaal RF and one shot everything.

Here's an example skill tree with just the right number of allocated points. Who even cares.
