3.21 Tectonic slam (help)

Hi guys, i suck on create builds, any 3.21 tectonic slam or any slam for marauder are viable for league start? Can't find anything, currently 2 years without playing

I have used this self assembled build on sentinel SSF with satisfying results, its not op build but I had tons of fun and beaten both the endgame dudes (exarch and eater, old league ones are too grindy to reach and I whas bored of ssf before).
Stack more than 1600 flat reg/s with spikes of 2500 and 90k armor (and still something imba can insta kill you, but its mainly safe for 99% of threats, even for HC). Also you run with 85-84-84 ele resists.

Key items,

Alt item for searing exarch: Rise of the phoenix that helps with the rolling balls and nasty floor stuff that decreases your max fire res.
