The character is skilled in the use of the javelin and knows the value of a well aimed throw.
When a character throws a Javelin and successfully causes damage to the target (after mitigation), the target location (either a limb or the body) is Speared. A Speared hit location is treated as crippled until the Javelin is removed, either as a Free Action inflicting the Bleeding (1) condition or as a Secondary Action requiring a strength test, which if successful removes the spear without causing further harm.
If the Javelin is blocked instead, the shield is Speared. A speared shield requires the wielder to spend one Stamina Point in order to even attempt to block with the added weight of the javelin. Removing the javelin from the shield requires the character to succeed on a Strength test as a Secondary Action.
