Regarding ranged weapon DMG. Do you DMG based on the ammo or weapon and size.

[LucasB]

So.. I have this x large crossbow bolt and shrunk the item with the spell shrink item to the size that will fit my light cross bow. Normally this x large cross bow bolt does 3d8 or 4d8 DMG when shot by a weapon of sufficient size. But since i have shrunk the item to the size that will fit in my light cross bow am I doing DMG based on the light cross bow or the x large cross bow? Since the item reverts back to its original size when it hits a solid object i.e. shrink item. it would mean it does DMG based on the x large cross bow bolt right or light crossbow bolt? How do I figure this out? I mean DMG is done by weapon size not based on the size of the ammunition used right?

Thanks for the help folks.

Ranged weapons are the lesser of the size of the ammunition when it hits or the size of the weapon that fired it. In this case you are doing the damage of your light crossbow.

See for example person and reduce person.

Regardless if its an x large crossbow bolt we always go by the weapon DMG based on what fired it. I figured as much because there is nothing in the rules on how a shrink item can be applied to ranged ammo and still do the base DMG as a ballista would do once it hits its target... I hate when players assume things when there is nothing in the book that can back up his logic. They just take spells from the book and bend them in hopes the DM would play dumb and take their word for it.
