Void heart is necessary to reach radiance or PoH. Grubsong and dream wielder are so attached to my build that they are before void heart (until I start attempting charm bindings at least) because between them I have ludicrous soul gain for 2 notches (recover ~50% of a mask/spell worth of soul when hit for a notch, ~6x soul gain speed from dream nail for a notch (higher soul/sec when spamming than the normal nail enhanced by soul catcher + soul eater + quick slash for 1/9 of the notches), both are equipped as soon as they are obtained and never unequipped except to train for the charm binding in the HoG). My spell build (for speedruns and godhome): baseline + shaman stone + spell twister + heavy blow + nailmasters glory (turns beasts den into a joke, replace swarm + glory with long nail when geo is useless) My white palace build: baseline + deep focus + quick focus (for the white palace and PoP)
My n00b nail build: baseline + quick focus + unbreakable strength + unbreakable heart (used for first few runs + steel soul)
My Baseline: grubsong + dream wielder + void heart + gathering swarm
