Abilities/Arc Bolt

Arc Bolt fills your Main slot. Projectile main ability of the spirit school. Base damage 24. Cast 6 ticks. Fires 1 projectile at speed 18 over 14 units, piercing 1.

You get it by equipping 34 bases across 10 lines: Apprentice Wand, Ash Wand, Ashen Wand, Bone Wand and Dawnwarden Wand and 5 more.

The draft can bend it 7 ways — Echo, Reach, Multiplicity, Area, Force, Duration and Critical — and cards that ask for projectile, chain, critical, on_hit, split and pierce will find it.

Between rooms it can be offered 139 cards: 30 written for it specifically, plus the 109 that any ability can take. Those cards can put Burn, Venom, Distortion, Brand and Chill on it, and attune it to Fire, Poison, Void, Holy and Frost.

5 Uniques are built on gear that hands it to you: Gatebreaker, The Divided Sky, First Frost, Doormaker and Sunward Volley.
