Arcane Charge

Appearance: This unassuming brick is made out of a clay and silver mixture. It weighs 3 pounds. When arcane energy is infused into it, a series of arcane runes appear on its surface. Arcane runes in the center will countdown the amount of time before the charge detonates.

To activate the charge, a creature must make a DC 15 Arcana (Intelligence) check. On a failure, roll 1d4. The charge will detonate in that many minutes.

On a success, choose an amount of time up to 5 minutes. The charge will detonate in that amount of time.

Upon detonation, the charge explodes with a 5th level Fireball and a 5th level Shatter.

Additionally, any damage dealt to a construct or structure by this item is doubled.
