Made a couple posts about me trying to make FR totems work and now it's in a position that actually feels really good.

This is my very first time playing a totem build, mind you. Feels pretty good to make a homebrew build that maybe one or two people play per league and actually make it viable for some of the hardest content in the game. Total investment is around 50 div I think.
Adding Mageblood is initially a pretty big dmg loss, simply because how strong Arn's Anguish is. But with a MB ruby flask you could easily sustain RF. But I'd probably first focus on getting power charge rings, that would skyrocket the dps. 30m guardian dps is definitely possible for this setup. Against large targets you can also put in Dying Sun for 50% more burst dps, slap on Pain Attunement and you'll go far beyond 30m.
Though I was also thinking about throwing out the entire power charge stacking setup, there are other ways to get lots of damage on this build.
Just a little showcase that FR totem is by far not as dead as I thought it was after 3.15 nerfs. Ofc this is nowhere near the power of 3.15 FR totem, but it still works. And FR is just one of my all time favourite skills in the game.
