Spikes: Any attacker making a successful melee strike on a boma beast immediately suffers 6D damage from the creature's razor-sharp spikes.
Background
These monstrous beasts skulk about the forests of Onderon, their massive bodies destroying the flora underfoot. Their mottled green skin allows them to blend into the thick forests and ambush anyone who ventures too close. Boma beasts follow a simple tribal structure, each tribe having its own pattern of skin coloration. They have sharp, spike-like bone protrusions used for defense, protecting the beast's vulnerable face and skull.
