Drar is a member of the Cult of the Absolute. Should the party conspire with Elder Brithvar against Nere, he would side with Sergeant Thrinn and the other novices of the cult and fight against the party.
Your attack summons thorny vines, dealing Weapon Damage and possibly Ensnaring your target.
Ensnared creatures cannot move and take 1d6Piercing damage at the start of each turn. An ally can use their Help Action to try and tear away the vines.
