Rewatched Doctor Strange. Let’s make the whip Happen!
You create a masterwork whip out of fire that will not burn you. The whip deals 1 point of fire damage in addition to normal whip damage. If the whip leaves your hand for more than 1 round, it turns to ash and the spell ends. This whip does not provoke attacks of opportunity. In addition, as a swift action, you can choose to use this whip two handed or one handed. When used two handed, you gain a +2 deflection bonus to AC but can not cast spells with somatic components. At 6th level, the whip functions as a +1 flamming whip and can damage enemies regardless of armor. At 11th level, you are treated as having the improved trip and greater trip feats when wielding the weapon.
