Eldritch Darts

The caster may use Arcanist in place of the Fighter skill for one versus test or for a single Attack or Feint action in a Kill or Drive Off conflict. It may not be used to roll for disposition. Once the sell is cast, the caster is unarmed. The caster may arm another weapon or spell in her possession between rounds.

Unerring: Against any weapon except bow, crossbow or sling, your Attack counts as versus an opponent’s Attack and is independent against Maneuver.
Battery: In addition to the opponent acting on your action, you may target one additional opponent with an action. You may distribute your Margin of Success between the two targets as you see fit. When you reach 5th level, you may also target the third acting opponent. Upon attaining 7th level,  you may target any and all opponents on the opposing team, even those that are not acting this round.
Powered by Rage: +1D to Attack if the caster has the angry condition.
Aetherial: Mundane armor has no effect on Eldritch Darts. Only magical armor and spells or prayers provide protection.

No test to cast is necessary.
