Tubby Custard's Spirit Geist Build

Lady Geist is really strong early but you can lose health really fast if you aren't hitting your abilities
IMO it is best to get soul drain 2nd as if you go for Malice (her 3) you can drain your own health really
If build order is glitched I go: 1--2--3--4--1--1--3--4--3--2--1--2--3--4--4--5

Go from left to right
Geist is unique in that she doesn't really require getting raw spirit as she amplifies her own damage with her malice (her 3)
Make sure to keep hitting enemies with it before you attack as it boosts your spirit and weapon against Her malice can only get 5 stacks but refreshers the timer if you get them
Also realize that the more spirit power you have, the more damage you do to yourself, so watch your health bar.

These are luxury but really put Lady Geist of the edge.

Getting these can really help with your ability to do damage or punish people who over extend.

If you are ahead these can be really good
But most are situational, such as the armors
Sometiems just having more health can be good as many characters are mixed damage types.
