hundred hand build

this is still a work in progress. The idea behind this is to use the astral mirror combined with as many cards that grant extra arcane slots as possible to provide as many hand slots as possible and then fill those items with as many hand slot items that sync as possible. the intent of this build would be to bulk up over time to then be able to overpower most anything I come across to act as an elite enemy killer later on. based on my understanding there is enough flexibility in this build that you could have a small secondary gimmick that easily syncs with this gimmick depending on how hard you want to lean in and could have a lot of different build options. I chose to have a build that would allow for the maximum number of hands possible assuming I could theoretically get all the needed exp. which took on the secondary gimmicks of being a tarot user and a spell buffer so I could be a secondary investigator while waiting to buff up but I think there is a version of this where you are a weapons/hand slot jockey using multiple sword canes or something.

I can have a maximum of 7;8;9;10 (14) hands based on calculating your(2) original hands plus each arcane slot from combining astral mirror with the following cards your original arcane slots (2) https://arkhamdb.com/card/09089 Binders jar 1 per enemy under card (2) https://arkhamdb.com/card/60410 Familiar Spirit (1) with charisma I can have 2 familiar spirits (2)

https://arkhamdb.com/card/54012 Moon Pendant: an accessory You have 1 additional tarot slot so you can have 2 hierophants, and they have 2? tributes. (2) https://arkhamdb.com/card/01695 Relic Hunter: you get an additional accessory slot. With 1 you could get 1 moon pendant and a binder's jar to allow for 2 hierophants and which both have a 2 ? tribute. With 2 you could get 2 moon pendants and a binder's jar to allow for 2 hierophants and an additional tarot which all have a 2 ? tribute.

the following additional tarot cards are up for consideration. https://arkhamdb.com/card/54011 The Fool • 0 exhaust Reduce that card's cost by 1. https://arkhamdb.com/card/05035 Four of Cups +1 willpower

these cards pay for their own hand slots https://arkhamdb.com/card/01070 Book of shadows X2 (2) https://arkhamdb.com/card/05112 Sign Magick X2 (2)

I'd love to hear suggestions for further optimization of this build or other builds? how would you maximize hand slot usage to synchronize? could you do a healer focused version? what if you actually used versatile to pull from other classes?
