For those who don't know the skittle challenge for darksouls is to Pvp in the forest and throw down 1 prism stone per invader you kill. The catch is you have to use all 99 prism stone without dieing. This build has lots of healing spells so u don't have to rely on humanity and Estas only. Feel free to change it to str based if u desire. Also if u summon a friend they have to add another 99 prism stone for a total of 99+99=198 invaders killed.
