Prickly Booster*
Source
Galaxy Exploration Manual pg. 14
Any booster you successfully use on yourself or an ally causes the target’s skin to sprout thorny projections for a number of rounds equal to your key ability score modifier, in addition to the booster’s other effects. Any creature who hits the target with a natural attack or unarmed melee attack takes 1d6 piercing damage; this damage increases to 2d6 at 8th level, to 3d6 at 14th level, and to 5d6 at 20th level.
