Null Flame

You create a 2-meter radius zone centered on yourself or a willing creature you touch. The zone moves with the target. No fire, magical or natural, can penetrate the barrier. Any fire within the zone is suppressed for the duration. Fire spells cast from within the zone take no effect. Fire effects outside the zone are unaffected - the zone suppresses fire within its boundaries only, it does not extinguish or create voids in its wake.
