Marksdwarf

From DwarfFortressWiki

Armed with crossbows and deal pierce damage from afar. A bolt does a fine job at piercing the internal organs of a creature while also doing some damage to outside parts. This is of limited use against creatures without organs, such as magma men. Occasionally a bolt will get stuck in a target; the only known use for this is that a wrestling dwarf may grab the bolt and twist it in the wound.

A marksdwarf who is forced into melee will use the hammer skill to bash enemies with their crossbow.

Immigrating Trappers often arrive with a Novice Marksdwarf skill. Immigrating and embarking marksdwarves bring their own crossbows and a limited supply of bolts.
