- Will I loose the set if I use the RAF XP bonus or XP potions?
- Can I use a boost?
The following will prevent you from receiving your Heritage Armor on an Allied Race character:
- Using the Character Boost service
- Purchasing a Faction Change or Race Change for that character
- Receiving granted levels from the Recruit a Friend In-Game Bonuses
That being said, you are able to use Heirlooms items and experience potions while leveling your Allied Race character and still receive your Heritage Armor.
