Blessed Light

All allies that are within the light cast by the targeted flame are under the effects of an improved Bless spell. The flame must be small like a torch, lantern or small campfire. If the flame is extinguished this spell ends immediately. Whenever a target makes an attack roll or a saving throw before the spell ends, the target can roll a d6 and add the number rolled to the attack roll or saving throw.

At Higher Levels. At 5th level the additional roll is a d8
