Yeah, but they're not that dangerous- since they come singly. A nonameskill weapon-fighter eats them up. Actually, my marksdwarf shot once, then beat it about with crossbow without hammer skill to death.
Eh... I think he got lucky with an early hit and then capitalized. They can be pretty ugly little shites, one on one.
Nah. The swordsdwarf, unarmored, also took one with no wounds. (Iron Longsword, no quality)
EDIT: lemme check the stat-ups. Extremely Strong, Extremely Agile, Tough. And Competent Wrestler now along with Swordsdwarf...and has a narrow snakeman tunic in one hand along with the sword

The marksdwarf is Perfectly Agile, too, just from yapping. That meeting hall to keep my surface sand active is working wonders...Axedwarf has two grimeling kills as well, with only no-name.
