Bilrost Sentry: With the duty of sentry for your people you are the first to defend.

• Sneak attack/Assassinate do not apply in this fashion.

Gjallarhorn:   As an Action, you may call on Heimdall's symbol to grant allies the effect of Foresight for 2 rounds.  The resounding noise goes across realms alerting allies and enemies of the encounter. Upon sounding this deafening call enemies in a 120 ft. cone and enemies must pass dexterity save as the sound erupts.  Enemies that fail the save take 5d8 force damage and winded or half as much on success.  Further more the call emboldens allies doubling their movement for the round and hinders enemies that attempt to join the fight.

• Can only be used once per long rest.
