Swap around the pyro spells however you like.
Want more spell damage? Swap in dat Dusk Crown.
Want to hit harder and for more poise damage? Swap Chaos Blade to Crystal Flamberge/+15 Claymore.
Want more defense? Swap Avelyn to Gold Tracer, Havel's Armour to Giant Armour and Iron Bracelet to Giant Gauntlets.
Want more range? Swap Chaos Blade for Demon Spear. Want more range off-hand? Swap the Grass Crest Shield for a Demon Spear and the Chaos Blade for an Ascended Flame, Gold Tracer or Crystal Rapier.
Moveswap between Flamberge/Claymore and Gold Tracer is especially vicious as is quick-swapping into Gold Tracer to finish after the initial stagger.
Swap Lingering Ring then use Power Within to give yourself 150 seconds of sweet Stamina regen and damage buffs with reduced leech (swapping Havel's Ring back in immediately after). You can even swap in Sanctus over Grass Crest Shield to further reduce PW's effective leech.
