Potion, common
Similar to the alchemist's fire, the arcane bomb is a thrown projectile that, upon impact, ignites an explosion of magical force. As an action, you can throw this flask up to 20 feet, shattering it on impact. Make a ranged attack against a creature of object, treating the arcane bomb as an improvised weapon. On a hit, the target takes 1d12 force damage and, unless they succeed a DC 15 Strength saving throw, is knocked back from the direction it was hit from by 5 feet and prone. Also, if any creature other than the target is within 5 feet radius of the explosive impact, they are also knocked prone unless they succeed on a DC 13 Strength saving throw.
Notes: Damage: Force
