Priest of Balthazar

General
A Priest of Balthazar offers Faction Rewards by allowing you to unlock hero's, runes, weapon upgrades and skills using Balthazar Faction points.

Every skill, rune and upgrade is available from every Priest of Balthazar, except for those in the Ascalon Arena and the Shiverpeaks Arena. However you can easily get access to all upgrades by making a PvP character who can reach the other locations.

Location
There is a Priest of Balthazar in every PvP outpost, at every Alliance Battle map and on The Battle Isles. Some have names, others are simple labeled with a generic "Priest of Balthazar [Rewards]".
