[SIZE=1]To defeat the sinister fiery arachnid you should equip Ebony&Ivory (hand guns) because when you jump in the air you get a fair amount of shots in on hes back which is rather effective. Keep on doing this untill your devil metre goes up and jump on hes back and plaster him with slashes from Alastor (electric sword). Keep up this technique untill the spider eventually dies. [/SIZE]
