Rod. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage plus 11 (2d10) force damage.
Beguiling Presence. The fomorian targets a creature it can see within 60 feet of itself. The target must succeed on a DC 17 Wisdom saving throw or have the charmed condition for 1 minute. An affected target can repeat the saving throw at the end of each of its turns and whenever it takes damage, ending the effect on itself on a success. If a target's saving throw is successful or the effect ends for it, the target becomes immune to all fomorians' Beguiling Presence for the next 24 hours.
