In Aion 2 Season 4, Complimentary Oath Coins are seasonal, farmable currencies you can’t buy directly with real money. They are tracked in-game as Oath Coin: Season 4 and are essential for unlocking exclusive seasonal rewards, catch-up gear, and special currency items. Experienced players know that actively participating in the season’s activities is the key to gathering them efficiently.

Here’s a simple guide on where and how to get your Oath Coins without spending a dime.

1. Season Missions

Daily and Weekly Missions:

Open your Season UI panel to check the current rotation of Season 4 tasks. Completing basic PvE activities, hunts, and regional objectives awards bundles of complimentary coins. Focus on finishing daily quests first, then tackle weekly missions for larger coin rewards.

Seasonal Progress Milestones:

Your mission points add up in the Season Progress Tracker. Reaching tiered milestones on the free path grants additional Oath Coins automatically. Make sure to track your points regularly to claim every milestone before it expires.

2. Seasonal Game Modes & Ranking Rewards

Arena Matches:

Participate in seasonal PvP Arena modes to earn points and climb the competitive ladder. Even mid-tier placements grant Oath Coins, but the real bonuses come from ranking high.

End-of-Season Rankings:

When the leaderboard closes, top-tier players in Grand Master or Challenger tiers receive massive caches of Oath Coins sent directly to their in-game mailbox. Depending on your rank, this can be 70k–100k coins, giving a huge boost for redemption in seasonal shops.

3. Capital City Season Shops

Shugo Merchants:

After collecting your Season 4 Oath Coins, visit the designated Shugo seasonal NPCs located in your race’s capital city. These merchants are the hub for exchanging coins for valuable items.

Redemption Options:

You can spend Oath Coins on catch-up gear, Ancient Crowns, Goblets, or daily reward boxes. Prioritize items that help with character progression first, then save for collectibles or event-limited rewards.

Pro Tips for Efficient Farming

Stack Missions: Complete daily and weekly missions in the same session to maximize coins without extra travel.

Check Events: Seasonal bonuses sometimes appear for Arena wins or festival participation—don’t miss them.

Use Mail Alerts: Keep an eye on your mailbox; end-of-season rewards are automatically delivered, and coins can expire if not claimed.

By combining season missions, arena participation, and shop redemption, you can maximize your Complimentary Oath Coins every season without spending a cent. Focus your efforts early in the season to stay ahead of the curve and unlock the best rewards before the event ends.
