Projectiles are objects thrown by you or a monster, or shot with a launcher.
Thrown objects
Any item can be thrown (and thus be considered a projectile) if the entity throwing it is strong enough. Use the [t]hrow command to provide a list of readily-thrown items. You can expand this list to include your entire inventory by pressing [*].
Thrown items may receive a penalty to hit if there is an appropriate launcher (see below) for the item

To get the most out of the ammunition projectiles, you need to wield [w] the corresponding launcher and then either throw [t] the ammunition, or quiver [Q] a stack and then fire [f] from that stack. There is no bonus or penalty for using the fire command; it is merely a convenience.
Breakage
Some projectiles are at risk of breakage if they score a hit. The chance of breakage is determined as follows:
- Calculate
chance = 3 + erosion - enchantment
, whereerosion
is 3 if thoroughly eroded, 2 if very eroded, 1 if just eroded, and 0 otherwise. If the projectile has both types of erosion for its material, use the greater erosion only; erosions do not add. - If
chance
is at least 2, the projectile has a(chance-1)/chance
chance of breakage. Otherwise, it has a 1/4 chance. - If the projectile is blessed, there is a further chance of is being unbroken, modified by the character's luck.[1] Multiply the value from step 2 by the value from the table below. The result is the total chance of the projectile breaking.
Luck Range | Exact Value[2] | Average Value |
---|---|---|
-13 to -3 | 0.987 | |
-2 to 2 | 0.740 | |
3 to 5 | 0.495 | |
6 to 8 | 0.25 | |
9 to 13 | 0.006 |
Breakable projectiles are:
- all arrows, including elven arrows, orcish arrows, silver arrows, and ya
- crossbow bolts
- darts
- shuriken
- boomerangs
- all gems and stones except the Heart of Ahriman
Daggers do not break, and as such are a favorite projectile for those classes that can gain skill in their use.
