What the title says.
Let me list a few of mine:
Hellborne
Chestguard of Justice
Agony
Infernal Brimstone
Hellforged Legplates
Demonbone Legplates
Crescent Moon
Lots of lvl 50 ones aside from Golem boots that are cool, aside from those:
Deathmarked sword and shoulders
Iceskorn Talons
Speeker for the Dead
Nightshade’s Reach
But most of all that flipping Havoc pistol that deserves a mention on top of the lvl 50 category… Screw that thing.
Devil Cage Hauberks.
2 characters at 85 and 7 legit drops of those things. Do they ever end?
Except for iceskorn and hellforged legplates and a deathmarked weapon I don’t have any of the things you guys have dropping a lot 
Mine are :
Voidwalkers
wraithwalkers
Venomspine greaves
stormtitan treads
grasp of unchained might
Death omen
Deathmarked weapons
lights defender gauntlets
Obsidian juggernaut
I really wish I could swap all those multiple drops out , sick of the RNG , I have no armour pieces from markovian , no Ultos pieces and I am 600 hours in , I thought PoE was bad for drops .
Worst one was that obsidian juggernaut , it was my first ever legendary and that was for completing log the first time at 50 , the quest reward , my next legendary did not drop until lvl 65 and yup it was the obsidian juggernaut
