Missile Weapon Damage

Following on from B/X Blackrazor's  class based damage I have adapted his table to my own liking. Not that I don't like JB's table - the table below is pure homage - but the deadly temptation in house rules is tweaking and then tweaking some more, until one can't stop tweaking. A wise master once said, "Once you start down the house rule path, forever will it dominate your destiny." 

CLASS	Thrown*	Sling	Short Bow	Long Bow	Light Crossbow	Heavy Crossbow

NOTES

Weapon Range

Short +1 to hit / Medium 0 / Long -1 to hit

Thrown weapons do the same of damage as their melee counter-part, as determined by class (though only small weapons may usually be thrown).  Ranges and effects of special thrown weapons and items are in Equipment.

Bows, whether short or long, may be loaded, aimed, and fired once in a single round if the wielder is not in melee, using normal initiative.

Light crossbows, may be fired at normal initiative in the first round, provided they are pre-loaded, thereafter they always strike last.

Heavy crossbows, may be fired at normal initiative in the first round, provided they are pre-loaded, thereafter they may be loosed last only every other round unless the wielder has a Strength of 18, gauntlets of ogre power, or the like, in which case they behave as light crossbows.
