Changed the rapier to a shotel for a few reasons and that is really just a personal preference if you like another weapon and you are good with it feel free to use it
Great build for pyros of all type if you want to fire surge to chaos fireball you can or Great fireball to black flame you can or if you want to equip 5 great fire balls and 4 fire tempe togethersts you can ;) plus the armor looks soooo good
