Does House Level reset, and why should I raise it fast?

Yes, House Level resets with each new Reign. And it matters, because it decides which Heirloom bonuses are active.

How it works:

• Your Heirloom upgrades stay unlocked forever (permanent).
• But their effect is only active if your House Level is high enough — and that starts from zero each season.
• House XP rises through chapter quests, events and daily login.

The practical consequence: early in a Reign, re-grind your House Level first to reactivate the Heirloom buffs you've already paid for. Otherwise you're fighting with dragons stripped of bonuses that already belong to you. Note: each Heirloom rank's Mastery bonus stays active at all times, independent of House Level.
