Arcum Tempestas

The Arcum Tempestii are created by charging a stave of ironwood with the essence of a storm. 

Arcum Tempestas fires magical arrows, which do 1d8 piercing damage, and does not require ammunition. It has a maximum of 4 charges, and restores 1D4 -1 charges at dawn each day.

• Storm strike: Upon finishing a long rest - set the bow's damage type : Thunder, Lightning or Cold.

As part of your attack action you may expend 1 charge to manifest one of the following effects:

• Gale strike: You may push your opponent up to 10' away in a straight line. (DC 8 + Proficiency CON save).
• Lightning strike: Attacks this turn treat 3/4 cover as half cover, and half cover as no cover.

Fickle is the sea: Whenever you miss an attack made with Storm, Gale or Lightning strike, the force of the attack is turned back onto you. The bow booms with a loud peal of thunder, you take 1D6 thunder damage, and are knocked prone.

Stormlord: In order to able to expand two charges to use both Gale and Lightning strike in a single attack action, you must, on different occasions (different days or combat encounters):

1. Use Lightning or Gale strike;
2. Use each type of damage (thunder, lightning and ice);
3. Experience Fickle is the sea.

If you expend the bow's last charge, roll a D20. On a 1, the bow crumbles into dust and is destroyed.

Proficiency with a Shortbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
