Vaal Bone Zone - Vaal Summon Skeleton Architect of Chaos
I wanted to share my starter for the Legacy of Phrecia event, a perma Vaal Skeleton Architect of Chaos. It features 100% uptime on Everlasting Sacrifice, even before grabbing Divine Flesh, high block and all charges via support spectres and everything is made with SSF in mind. I also included a trade variant that is just a proof-of-concept to see how far the theoretical DPS could be pushed (it's high).
Disregard the names of my setups, since I can't change them they aren't really reflective of what they contain.
Two out of three support spectres can be found during acts, the third requires Ritual. You can easily push your spectre gem to level 25 which grants you a fourth spectre, I have not included this since I like to plan around three which you get without extra levels, but there are many good options for defensive/support spectres. It also does not feature an Animate Guardian, I rarely bother with AGs in SSF since the gear is bothersome to come by, but there is socket space for one should you wish.
Damage is awkward to estimate, but you will summon over 40 minions at the time which all do over 100k dps each with modest gear, I've tried my best to scale damage generically and in most setups there are no wasted links. I have not tested the skill so I can't vouch for how reliable it is to have all minions attack the same target at once, I will experiment using both Feeding Frenzy and Signal Prey.
If you can spare the affixes, consider benchcrafting "# Armour during Soul Gain Prevention" as showcased by UberDan, this will give you stupid levels of armor whenever you cast Vaal Summon Skeletons.
