You will defeat a certain boss shortly after about, I'd say, halfway through. When you see 'right of kindling acquired' then I believe yo can go to 20 flasks at a bonfire for three humanity. When you start a NG+, that bonfire would remained kindled as well.
There's a boss deep in the catacombs that will drop the rite of kindling that will let you do it. I don't suggest going down there until your around lvl 40-50, there are necromancer that keep reviving the skeletons down there you have to kill them to stop
them, you can use a divine weapon on the skeletons to stop them from getting up but to stop it permanently you have to kill the necros. Once you kill the necros they don't spawn back

at less than level 20, considering you made yourself a divine weapon already. I go down there all the time now around level 10 without faith characters.
I usually go and fight that boss first even, before fighting the tarus demon. I know a couple short cuts. Jumping down that pit in the center, and you can bypass most of the level and fall right into the area here the rolling skelentons are. the boss name
is PINWHEEL. and its a pretty weak boss too. even at level 10 or so, still kicks it's @$$
