Multiattack

The far darrig makes four antler glaive attacks.

Antler Glaive

Melee Weapon Attack: +4 to hit, reach 5 ft. or 10 ft., one target. Hit: 7 (1d10 + 2) slashing damage and the target must make a successful DC 13 Strength saving throw or either be disarmed or fall prone; the attacking far darrig chooses which effect occurs.

Enchanted Glaive Maneuvers

A far darrig can magically extend or shrink its antler glaive as a bonus action to give it either a 10-foot or 5-foot reach.
