I tested the damages on the regular hollows near Firelink.
At the time, i was testing with the Crown of the Dark Sun, Dusk Crown, Logan's Catalyst, Bellowing Ring and 45 Int.
HCSM
CoDS = 245
CoDS+Bellow = 307
Dusk = 272
Dusk+Bellow = 339
Dark Bead
CoDS = 286
CoDS+Bellow = 367
Dusk = 323
Dusk+Bellow = 411
Even with all the sorcery boosting equipment, isn't the damage a little too low? In case anyone is wondering, i'm using the new bbg method for testing my builds.
