Ancient Vows is an optional Act 2 quest in Path of Exile 2, but it's one that every player should complete. Although it doesn't take long to finish, the quest rewards you with a permanent character bonus that remains useful throughout the campaign and into the endgame POE 2 Orbs.

The quest revolves around finding two ancient relics, bringing them to a hidden altar, and choosing a passive bonus that complements your build. Better yet, your choice isn't permanent-you can switch between the available rewards whenever you need.

How to Start Ancient Vows
The quest begins automatically after you pick up either of these quest items:
• Sun Clan Relic
• Kabala Clan Relic

These relics drop randomly while exploring Act 2.

You'll typically find them in:
• Sun Clan Relic – Dropped in The Bone Pits
• Kabala Clan Relic – Dropped in Keth

Since both zones contain plenty of monsters, fully clearing each area usually gives you a good chance of finding the required relic before moving on.

Complete the Quest
Once you've collected both relics, head to the Valley of the Titans.

To finish the quest:
1. Travel to the Valley of the Titans.
2. Locate the altar near the waypoint.
3. Place both relics into the altar.
4. Confirm your reward choice.

After completing this step, you'll immediately receive your permanent bonus.

The altar remains available, allowing you to return later if you want to change your selection.

Ancient Vows Rewards
Completing Ancient Vows grants +1 Charm Slot along with one of two passive bonuses.

You can choose between:
• 30% Increased Charm Charges Gained
• 30% Increased Charm Effect Duration

Since the choice can be changed later by revisiting the altar, there's no need to worry about making the "wrong" decision.

Which Reward Fits Your Build?
Each reward supports a different playstyle.

1. Increased Charm Charges Gained
This option is useful for players who:
• Trigger charms frequently.
• Want faster charge generation.
• Prefer more consistent defensive or utility effects.
• Play fast-paced mapping builds.

Because your charms recharge more quickly, you'll be able to activate them more often during combat.

2. Increased Charm Effect Duration
This reward works well if your build benefits from longer-lasting charm effects.

It can be helpful for:
• Defensive builds.
• Boss encounters with extended fights.
• Characters relying on resistance or utility charms.
• Players who value longer buff uptime over faster recharge.

Fortunately, you can switch between the two bonuses whenever your build changes.

Tips for Completing Ancient Vows
The quest is fairly straightforward, but a little preparation makes it even easier.

Keep these tips in mind:
• Fully clear Keth and The Bone Pits instead of rushing through.
• Upgrade your gear before entering tougher Act 2 areas.
• Prioritize life and elemental resistances while leveling.
• Return to the altar later if your build evolves and another reward becomes more useful.

Following these simple steps helps ensure you complete the quest without unnecessary backtracking.

Why Ancient Vows Is Worth Completing
Many optional quests provide temporary rewards, but Ancient Vows offers something that benefits your character for the rest of the game.

Its advantages include:
• A permanent account-independent character upgrade.
• Flexible reward selection.
• Useful bonuses for nearly every build.
• Quick completion during the main campaign Exalted Orb buy.

For such a short quest, the long-term value is excellent. Whether you're leveling your first character or optimizing a new build, Ancient Vows is a quest that's well worth completing before moving on to later acts.
