BackBlast (EFA - B)

Originally created by the phaerimm, it can now be found in spell books across Faerûn. For the duration, if you roll a 20 for a saving throw against a spell, and the spell is 7th level or lower, the spell has no effect on you and instead targets the caster, using the slot level, spell save DC, attack bonus, and spellcasting ability of the caster, except that backblast turns only spells which deal fire damage that target you. Once backblast turns
a spell, its duration ends
