The Not So Magic Greatsword Build

This build is not perfected, but here's what I have so far

Hello everyone, I love this game and have found a rather interesting sword that I thought I'd make my own.
This build's main feature is the Spectral Sword, it's main effect is increasing physical damage by 1% per missing mana point; coupled with the druid's bane armor, I use the boots, to fully inhibit mana regeneration.
I put my stat points into the bare minimum to equip and wield all parts of the build, then dumped the rest into spirituality to increase max mana.
Equip whatever rings, amulet, gems, and back piece you want idk man.
Also I have a spell I use to just drain all my mana after a rest.

I have upgraded the sword and all the armor a bit and will include the + values in the rundown below:
Spectral Sword +10
Increases physical damage by 1% per missing mana point
2 Starborn Eggs attached for 20% weapon damage
Abandoned Helmet +5
Increases physical damage by 30%
2 Sapphire Weaves attached for 20% increased max mana
Duel Knight Gloves +8
Critical hits restore 10 stamina
Increases melee damage by 36%
Duel Knight Cape
Increases stamina regeneration by 25
Increases crit chance by 10%
Revenant's Ribcage
Weak spot damage 20%
Melee damage 20%
Gem of Dodge 10% dash cooldown reduction
Gem of Stamina x1.2 stamina recharge rate
Rogue's Step +7
Increases Dash speed by 30%
2 Gem of Dodge for 20% faster dash cooldown
Druid's Bane Boots THESE MAKE THE BUILD WORK
Receiving magical damage refills all dashes
THE IMPORTANT PART: Fully inhibits mana regeneration.

Reduced armor weight until I hit medium armor for a bit nicer quality of life and dashes.
In summary I use dashes and heavy attacks to do hit and run nonsense with a greatsword. Important note with greatsword heavy attacks: you can hold them as long as your stamina allows before swinging.
The total increased damage is this.
Including missing mana: Physical Damage 345%
Weapon Damage 20%
Melee Damage 56%
So in theory without resistances calculated a total of 421% increased damage done. This is without the two handed or any other skill trees calculated, no sneak damage calculated, no heavy attack damage calculated, and no other nonsense involved.

I hope you get the idea and are inspired to find unique items to make fun builds with!!
