Abilities 4 of Monstrosity: Seamripper
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.
Maim
Orn v4.0
An arm which is Maimed may not be used to deliver any combat effects in Melee or to throw packets until it is renewed. Two Weapon and Two-Hander triggers may not be used if either arm is affected. You may continue to use basic melee attacks and defend with a weapon wielded in that arm as normal. Since you cannot use combat abilities with it - you cannot use counters to things delivered to that weapon. If you are dual wielding but not using the Two Weapon Trigger, you can still deliver abilities through the other arm.
A leg which is Maimed inflicts the character with the Flaw “Always Slowed” until it is Renewed. You may not use any mobility effects while under this effect (Dodge, Charge, Retreat). If you are dual wielding but not using the Two Weapon Trigger, you can still deliver abilities through the other arm.
You cannot use the affected limb until it is Renewed. For safety reasons, you must drag a Maimed leg rather than hopping on it. If both of your legs are Maimed, you cannot move.
