Ice Dagger

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

Icy Shortbow

Ranged Weapon Attack: +5 to hit, range 80/320 ft., one target. Hit: 6 (1d6 + 3) piercing damage plus 5 (2d4) cold damage, and the target must succeed on a DC 13 Constitution saving throw or suffer one level of exhaustion from the arrow's icy chill. On a success, the target can't suffer further levels of exhaustion from any beli's Icy Shortbow for 24 hours. If a creature would suffer a sixth level of exhaustion from this attack, it is reduced to 0 hp instead and must make death saving throws as normal. A creature reduced to 0 hp in this way can't suffer further levels of exhaustion from any beli's Icy Shortbow for 24 hours.

Invisibility

The beli magically turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the beli wears or carries is invisible with it.
