How do you raise your House Level in Dragonfire?

House Level goes up with House EXP, earned mostly through:

• the daily login (steady House EXP),
• Chapter Quests,
• events.

Its role is crucial and often misread: House Level decides which Heirloom buffs are ACTIVE. Your Heirloom upgrades stay unlocked forever, but you need a high enough House Level for them to actually work.

⚠️ House Level resets every reign. So at the start of a season it's one of the first things to re-grind, just to switch back on the buffs you've already paid for. The daily login also hands out Valyrian Tablets (a Heirloom currency), which makes it a daily habit worth keeping.
