Managed to complete my atlas with this build. The gear isnt perfect since its a ssf character. There are two setups - one with windscream (for bossing) and one with bubonic trail (for mapping). There are some other swaps I usually do depending on the boss im about to fight, like swapping the jade flask for ruby / sapphire or whatever else is needed. The only thing ive struggled with was the ziggurat boss (Nightmare of Catarina). The arena there feels too small for me, but I'm sure someone younger could manage to manoeuvre in it.

Its a pretty solid build, even without the mageblood (using 100% darkness enthroned, damage is pretty similar, but speed isnt)

There are of course other ways to play it, like going evasion / armor for more tankyness or anointing panopticon / watchtowers and going for 3rd cluster and dropping bastion of elements for heart of destruction if you want something more glass cannony, but I like the current version.
