Kingmaker: The Rise of Stormgaard
When strung from Hassan's longspear, it's heraldic imagery mysteriously changed to the House Helbrester coat of arms.
Once per day it can be used to provide Heroism (per the spell) for one hour by slamming the butt of the spear (or whatever weapon it may be attached to) on the ground and issuing the command word. The weapon does not need to be wielded in combat to reap the benefits of the spell.
- Heroism: This spell imbues a single creature with great bravery and morale in battle. The target gains a +2 morale bonus on attack rolls, saves, and skill checks
