Bramble Bomb

Optional featureValdaSpire242014
Feature type
BF

By adding soil and a potent fertilizer to your Bomb's explosive contents, you can change it into a Bramble Bomb. This Bomb deals no damage. When you use the Bomb's Explode property, each creature within the explosion makes a Strength saving throw, instead of Dexterity. The area of the explosion is filled with thorny brambles and is Difficult Terrain. A target on the ground hit by this Bomb or that fails its saving throw against it is entangled in the brambles and its Speed is 0 and can't increase. An entangled creature can take an action to make a Strength (Athletics) check against your Alchemist save DC. On a success, it frees itself from the brambles and its Speed is no longer 0. The brambles shrivel and die after 1 minute.
