[Build of the Week] SillyIsLily's Mana Stacking Thorns Infernalist

My Baby for the league so far has been a Mana Stacking Thorns Infernalist
This is a build that was not viable before 0.3, but with the Icetomb buffs that we got with the patch mana and thorns are now best friends!

We go infernalist for life/mana stacking from Beidat's Gaze and over 400% crit multi with Grinning Immolation
On the high end the build can get up to over 3700 mana which, with a corrupted Icetomb, can work out to over 800 flat thorns damage before increases, and we still get to take advantage of other sources of thorns like Scavenged Plating, Greater Runes of Tithing and rare modifiers
We also get to use the mana as a health pool using Mind over Matter to get up to 7k Phys Max Hit and 20k Elemental Max Hit and we can use Mana Remnants to almost instantly recover from big hits, making the build extremely tanky too!
Using Resonating Shield and Rapid Assault with Quillburst and Barbs we can apply our thorns damage on hits to quickly and efficiently blow up entire packs of enemies, and it's a joy to let thorns delete bosses with faster attack speeds!

The build is simple, tanky, has good DPS, uses two button gameplay and has almost no screen clutter (less lag anyone?)

The only caveats are that it is noticeably slower than Deadeye and can struggle against slower hitting bosses like Xesht

You can see a video explaining the build, including clips of it in action here: https://youtu.be/z9nnstKENBY

I have plans to push the build even further and you can keep track of that on my Twitch and in my Discord, both of which are linked in the video description :D
