Chiroptera Dagger is a Level 38 RARE/EX dagger that is dropped in Phoemina Aqueducts, which of course is a Level 40 cap. It is dropped by the NM Tres Duendes, which is a cluster of bats. People say the spawn time is pretty dang good because apparently it seems to spawn with Fomor type things. I would like to grab this dagger so a party of 40's would be nice. Anyone?
