Arcane Charge

You touch a small object that fits in your hand, no bigger than a foot long in any direction, weighing less than 5 pounds. You charge the item with Arcane Energy, causing the item to explode after a number of rounds equal to your Will score or when it strikes a person or object dealing 1d4 Arcane Damage. You can spend 1 additional Stamina to make a ranged attack against a target within 30 ft. of you, adding 1d4 Arcane Damage Dice to the attack when you cast this spell. Increase the number of Arcane Damage Dice for each Stamina spent past the first.
