To he who finds this, know that I, Acilius Bolar, last of the Blades to survive the attack on Cloud Ruler Temple, took refuge here, in this ancient sanctuary. The Thalmor have come for me, but they shall not desecrate this place. I go forth to meet my death with honor. If you are worthy, take up my blade and do the same.
Bolar's Oathblade is an Akiviri Longsword wielded by an Imperial named Acilius Bolar, once a member of the Imperial Guard group called The Blades.
While wielding this blade, you have the ability to intimidate your foes in combat. On a successful hit, your target must make a WIS save (DC: 8+prof+your STR or DEX). On a failed save, the target becomes frightened of you until the end of your next turn.
