Hmm, I might, Treyus was a pretty interesting character, and companion, she wasn't evil or good necessarily

@Dragonborn1721: about Susanoo I got the same idea, Dragon Aspect is the key to unlock the true power of that jutsu. About Alchemy you're right, I was thinking about Lingering Damage and Shivs as weapons to emulate Tsukuyomi (like when Itachi torture Kakashi for 72h in 3 seconds real time). @Chris: maybe the good old fashioned Quick Reflexes + Slow Time combo (blocking with only a kunai/dagger) could work well to emulate the enanched reflexes and the predictive abitilities of the Sharingan, but I'll work on it.

Check out the Nordic carved armor. Theres also a bit of pelt on the cuirass.

Miraaks staff spreads tentacels that look like Amaterasu ;).

I'll join too with a demonhunter inspired by Van Helsing.

@Relycs: nice thought, but that deals poison damage and Amaterasu is more like flames. Actually I don't how to replicate the dark flames, any thoughts?

Ahzidal´s Ring of Arcana maybe?

Yes it does poison dmg but the enemy will be knocked back and get covered in a dark substance. Man come on, forget the poison, its just too good to pass by. Trust me, theres nothing in the game that is like amaterasu, except Miraaks staff/Robe and Moras Agony. And like Karver mentioned, you can combine the staff with ignite for the flame effect.

Maybe you're right: I'll do some tries and see what comes out.

Maybe you should check the Veridian Witch Build which uses Miraaks stuff.
