Draconic Duel

Arkan uses his elemental affiliation alongside a divine gift in form of a temporary power boost to septa-wield his five javelins alongside his standard weapon by controlling them via a mix of magnetism as well as plain magic and willpower, making them float around him and be moved around as well as returned to him at will. Half of his hit points will be sacrificed and cannot be restored until the spell has ended. When attacking, Arkan can choose to either use javelins to aid an attack roll by adding a 1d6 for each "assisting" javelin or use javelins for a separate strike or throw, though they will be returned to Arkan after the attack has ended. 

This ability can only be used if a long rest occurred in a reasonable timeframe (aka about a day or so, a day and a half at a maximum) and has a recharge time of a day and a long rest.

If Arkan's hit points are below 25% when casting Draconic Duel, he will only be able to perform actions for 1 round before immediately falling unconscious and having to roll death saving throws. If Arkan's hit points are below 50% percent when casting Draconic Duel, he will have to roll a constitution saving throw against the current round number at the beginning of the 3rd, 4th, 5th, 6th and 7th round after the initial casting. If his hit points are below 75%, this only applies to the 6th and 7th round.
