Abilities 6 of Beast: Griffin
Unarmed
You trigger an Unarmed ability by attacking the intended target with an Unarmed Attack. If you do not have the Proficiency to use Unarmed Attacks, or that arm is Maimed, you cannot use the ability.
Pin
You cannot move or use abilities that require movement (e.g., Sign, weapon attacks, most supplies) so long as the user holds you. If the attack was delivered in melee, the user must hold their weapon on you. Otherwise, they must hold a hand up toward you. The effect ends if you are hit or the user attacks, moves, or uses an ability other than speaking.
Twin
A Twin ability includes the "Twin" prefix as part of the tagline and is delivered by attacking two separate characters with separate weapons in either hand. Both characters hit are affected. If the same character is hit by both attacks, that character is only affected once. If this makes the target ambiguous (e.g., Twin Disarm on two different weapons or Twin Maim on two limbs), the affected character chooses which target is affected.
