- Reward for reaching rank 3 in the Brotherhood of Blood.

This is likely one of the harder spells to obtain in NG and NG+ due to the way advancement works within the Brotherhood of Blood. However it is also one of the most damaging, if not the most damaging, pyromancies in game.
The Great Chaos Fireball is very similar to Great Fireball; it is an arced projectile dealing heavy fire damage. However, the difference between these two spells is that Great Chaos Fireball deals higher initial damage (tested on various enemies in NG++) and leaves a short-lived pool of lava on impact as well.
