Dark Souls Remastered | Pinwheel boss fight, solo on NG+1 (NG+)

Killing Pinwheel is needed to gain the Rite of Kindling. Without this rite, a bonfire can only be reinforced once, allowing 10 Estus Flasks. With the rite, it can be reinforced two additional times, up to 20 Estus Flasks. All kindled bonfires stay permanently kindled up to that state (10, 15, or 20 Estus Flasks), including in every new playthrough.

Drops:

60000 souls
1x Rite of Kindling (see above)
1x Humanity
1x Homeward Bone
Mask of the Mother
