Projectiles are objects thrown by you or a monster, or shot with a launcher.
Thrown objects Edit
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 readilythrown 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
Launchers and their ammunitions Edit
Launchers and their ammunitions  

Launcher  Ammunition allowed 
Sling 

Bow 

Crossbow 
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.
BreakageEdit
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(chance1)/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  $ \frac{197  4 \cdot Luck}{200  4 \cdot Luck} $  0.987 
2 to 2  $ \frac{148  3 \cdot Luck}{2004 \cdot Luck} $  0.740 
3 to 5  $ \frac{99  2 \cdot Luck}{2004 \cdot Luck} $  0.495 
6 to 8  $ \frac{1}{4} $  0.25 
9 to 13  $ \frac{1}{2004 \cdot Luck} $  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.
