Oh stuff! Okay lol. Cool. Which pyromancies are you using? Which pyromancies did you use to beat 4kings.
Great Combustion was the primary.
8 charges with my setup kills one king, and dusk crown gives you enough for 2 kings. Easy kills.
Other pyromancy was Power Within. Normally put it on immediately after I killed the second king, to avoid losing too much health, as I didn't really need it for the first two.
Once you get a hang of their attacks, it's actually a pretty simple fight.
EDIT: Wait, It only gives you 12 charges.
I guess it only takes 6 to kill a king with the setup then. xD
