6.86 "Pro" Abaddon

Since Storm Spirit is not a thing anymore, go ahead, knock yourself out with ARatdon. Most people are not gonna catch you.

Though it's rather slow, but still faster than something a ratting Ember or Tinker could do.

Actually Ember Spirit and Tinker are still faster rats because they kill creep waves more quickly. Ratting isn't just about tower damage, it's about applying pressure. Killing creep waves fast applies pressure.

I still find Ratadon a weird idea, if only because the hero is significantly better grouping up with his team than applying solo pressure.

ARatdon is totally not playing Abaddon to his potential, if you're ratting, you're often alone which means there will not be people to heal or stuns to remove.

But it's something you could do, it's mainly just another option, kind of like the Nature's Prophet who builds teamfighting items like Mek. It's not what he's best at, but it can still work if the game favors it. ARatdon is something to do if teamfights aren't really winnable anyway but you find yourself in a decent farm position.

Do you know what Curse of Avernus does?

Its perfect for pushing waves
