Effects of missiles and thrown weapons

Due to safety limits placed on these weapons and the low mass of the ammunition, they are designed to typically strike with less force and need not strike with the same force as hand-held weapons to be considered a killing or a good blow.
1. This does not transfer the responsibility of judging the effects of blows to the archer, as it is left to the honor of the combatant being struck by the weapon to judge the effects.
A missile or thrown weapon that strikes you on a legal target area and is properly oriented (i.e. with the point, blade or striking surface) is considered good.
Be aware that the effect of the blow depends on several factors, including target area, weapon strength and type of munition.
Be aware that weapons (bows and crossbows) that are under-powered may not deliver enough force for a fighter to notice a hit in battle.
Missiles (e.g. siege munitions, arrows and bolts, and thrown weapons) are considered spent when they strike their first target, the ground or a battlefield structure.

Siege-class missiles that have struck you can be identified as siege-class missiles as they are primarily yellow. They include ballista bolts and simulated rocks (1 pound (450 g) foam or 4-tennis-ball clusters).
A blow from siege class missile to your shield is fatal or completely disabling, unless otherwise specified by scenario rules.
A strike by siege-class munitions from another siege engine destroys the struck siege engine.
Handheld weapons struck by siege-class missiles are considered destroyed and unusable.
Standing pavises are destroyed by a single hit from siege-class missiles.
1. If you are behind a pavise that is struck by a siege-class missile, you are not killed, but the pavise must be immediately removed from the field or dropped flat.

Small-arms munitions include single tennis balls and tubular-shafted combat archery arrows and bolts.
Small-arms munitions fired from siege engines have the same damage and effect as combat archery projectiles, and are effective against the legal target area they strike.

Combat archery arrows and bolts are effective against the legal target area they strike.
Ranged combatants should be aware that missiles launched against especially heavy armor might not be noticed by your target. In which case, give your target the benefit of doubt.
If your missile strikes with anything other than the point, you should call, "No good!" or "Haft!" to your opponent.
