Is this the updated version ?
If you have enough strength to put on spirit monarch , getting 10 strength in demon circlet , Amy or tome can let you swap in wraithstep
Yes that's the updated build, and you can get +strength on prebuff tome, amulet, skill charms or circlet, which could be as simple as 2x fal runes in circlet. And you can also use an ethereal monarch spirit swap and ethereal wraith steps, which brings max strength needed down to 153. You can easily get away with a base strength build, but statting some minimal amount with imperfect gear doesn't hurt much
The main variants on gear are a pretty small change of
>shako vs coven (coven for a cheaper setup)
>maras vs 2/20 fcr amulet (must be 20%, and has less QoL but higher blood boil dps, a dubious tradeoff at high cost)
>2x sojs vs sling + fcr ring (could be crafted caster or just mana+fcr and mf/resists)
You only need to get 20% fcr from one of these three. So the cheapest setup is Coven + Maras + Sojs, which is also +1 teleport overall, still getting 40% mf
But the highest QoL is Cham Shako + Maras + Sling + Fcr, which can be a whole ton of mana, +life, 10% dr, 95% mf, cannot be frozen and maybe some resists, and +1 teleport oskill
Sling setups need you to swap rings while prebuffing, but save you needing to swap a tome of tp, so it works out about the same amount of clicks
