I dare you to

And here we are again, after almost half of a year. I started this league as duelist and have just got shattering steel of ammunition from my first lab (ofc i was rolling 1d7 and 1d3 for this).

Should I upload any videos to confirm my character and skill and, if yes, how do i do this?

About shattering steel of ammunition: current progress is here https://pobb.in/NhnaaRlBmXDw
My idea is to use penance mark on bosses to spawn additional enemies, and then to deal damage with "call of steel", that damage enemies in AoE. However, I really have no idea if this is working or not. I guess i'll focus on getting more survivability and damage.

Upd.: seems like I'm close. If shattering steel aoe is same as call to steel explosion, i have 4 out of 4.5 meters if i crit recently (i guess i do). That's still not enough to explode the boss, but map clearing is insanely good.

Upd. 2: i decided to rebuild into sword + crits because increasing AoE is very expencive, takes some equipment slots and is VERY conditional (boss must be standing still so that call of steel explosion works). Updated PoB: https://pobb.in/XtFFnchash6Y. Yes, i know there's only one ring. I'll get second one as soon as i stop being lazy.

about 70% of this challenge is done: Eater of the worlds was finally defeated with 0dps build.

A bit of explanation: i turned off steel shards (~220% more damage at close range) and molten shell (i guess one can use it during "Inescapable doom" to avoid some damage). I don't count frenzy charges just like poe.ninja (however, i have them during the boss fight because of sword mastery).

I'll be prepearing for the exarch fight, especialy his fireball phase (right now i die if i touch a fireball). It'll be very likely i gonna run this challenge again after defeating exarch, but there are no promises.
