Ice Dagger

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage plus 2 (1d4) cold damage.

Icy Shortbow

Ranged Weapon Attack: +5 to hit, range 80/320 ft., one target. Hit: 5 (1d4 + 3) piercing damage plus 2 (1d4) cold damage, and the target must make a successful DC 13 Constitution saving throw or gain 2 levels of exhaustion from the arrow's icy chill. If the save succeeds, the target also becomes immune to further exhaustion from beli arrows for 24 hours (but any levels of exhaustion already gained remain in effect). A character who gains a sixth level of exhaustion doesn't die automatically but drops to 0 hit points and must make death saving throws as normal. The exhaustion lasts until the target recovers fully from the cold damage.
