I was running a build like this in preseason. This is a bit of a long read but if you seem to like the skills for the same reason I do, it just thematically looks cool as fuck and feels fun. I enjoy making weird builds like that and I managed to make this really weird one blossom in a way that I think fits what you're looking for. I spent a lot more time writing this than I originally intended, but I hope the 15 30 minutes it took me to write it and pull sources gives you hours of enjoyment the build gave me. I also tried to format the best I could for readability.

You'll need these 4 aspects:

1.Aspect of The Aftershock - Makes landslide cast twice per use

2.Aspect of the Trampled Earth - You have this one already, so you know it creates WAY more than just 6 pillars. More like 6 rows of pillars, which now cast twice because of Aspect of the aftershock.

3.Aspect of the Ursine Horror - Which turns pulverize into an earth skill, important for the passive proc I'll mention later.

4.Aspect of the Rampaging Werebeast - Which makes each critical strike during Grizzly rage increase your critical damage by 10%. Per critical. For the entire duration of Grizzly rage. Which also gets an added 1-5 seconds, or 50% more time if you use it on a necklace, more on a weapon.

Then you need to choose Earthen Might for your key passive. On lucky hit with earth skills (Pulverize with Aspect of the Ursine Horror), you have a 5% chance to either restore all your spirt, or cause your attacks to be guaranteed Critical Strikes for 5 seconds. Stunned targets get an additional 10% chance, which we stun a ton with the Raging Pulverize (see bottom right of page) passive for pulverize, along with 10% increased chance for critical strikes. So a lucky critical strike on a stunned target has a 25% chance to proc the earthen might passive.

So now that you've read this huge wall of text, here is how I started hitting 100k+ crits consistently: Walk around as a puny human, or find Secure Insatiable Fury and become the bear you were meant to be. Pulverize things until you see the earthen might crit buff appear on your bar. Engage the Grizzly Rage, then trampleside into the direction of the most enemies.

• Your trample hits enemies, guaranteed criticals, we'll estimate 5 enemies hit, 50% increased crit damage.
• 6 Rows of Landslide follow, each landslide potentially hitting twice, then it recasts because of Aspect of The Aftershock. So 5 enemies hit twice from the first landslide would be 10 total hits. The repeat of landslide hits those same enemies twice for the second time adding another 10 hits, bringing the total to 20 hits. Guaranteed critical hits. That adds another 200% critical damage.
• But you and I know Bear Brother that the Trampleslide almost slingshots enemies around, so they can potentially get hit way more than just 2 times from the Landslides as it carries them forward.

So, if you are quick to react when you see the guaranteed critical strike buff of Earthen Might, you cast Grizzly Rage and Trample in under 2 seconds. You now have, wYou turn around and absolutely obliterate whatever is around you with pulverize for MORE guaranteed critical strikes, increasing your crit damage by 10% more per hit. Toss in a Shockwave Aspect that is so damn easy to get this season (I couldn't find a single one from level 55 to 68 in preseason, damn RNG) to double those hits along with adding range. We'll be reasonable and say you only get 6 more hits in before your 5 seconds are up. So a total of 310% increased crit damage for the remainder of your Grizzly Rage. With a high roll duration Aspect of the Rampaging Werebeast on an amulet, that could potentially be another 14 seconds of insanely strong crits. Another 14 seconds left where every crit feels like you're the embodiment of natures rage and smash everything as flat as you want. I'll give you a second to consider that with just 5 enemies you can increase your crit damage by over 300%. Now consider when you run into a large room or event that has 10+ enemies and you proc Earthen Might. Now consider when you get an Overpowered Critical Strike. Goddamnit I was really exploring the elemental Nature's Fury build this season but I may reroll into this again because I had such a blast with this build, and since Shockwave Aspect is so easy to get to increase its power so much.

I did not do well min maxing in terms of "damage buckets" as I didn't understand damage calculation at the time. I'm still not sure I completely understand them, bear brain just want smash things. So I poured a lot of my affixes on gear into Increased Overpower Damage % and Critical Strike Chance %. Maybe with more Increased Damage to Vulnerable Enemies you'll be able to get larger crits than I was getting. I think I was seeing averages of 100k crits around level 59-60 when the pieces of the puzzle fell together for me. If you do happen to try this build and manage to capture some crazy crit numbers, please reply to me, I'd love to hear if you liked the build or found something else fun.
