ODIN Valhalla Rising is a visually stunning MMORPG that offers a deep world filled with Norse mythology, epic boss fights, and expansive open-world exploration. While many players focus on leveling up or collecting rare gear, there’s another layer of accomplishment that often goes unnoticed—achievements. Some of the rarest achievements in the game aren’t just about grinding or luck; they require smart use of resources, particularly ODIN Diamonds. If you’ve got some Diamonds saved up or are planning to buy ODIN Diamonds, here are seven rare achievements you can aim for.

1. Master of Fashion – Collect 50 Unique Costumes

Unlocking 50 different costumes is no small feat. While some outfits can be earned through quests or events, many of the more exclusive ones require purchases from the in-game store. Using ODIN Diamonds wisely here can help you access limited-time or seasonal outfits that count toward this rare achievement.

2. Pet Whisperer – Acquire 10 Epic Pets

Epic pets not only look amazing, but they also offer stat bonuses that can make a real difference in high-level PvE or PvP. Since epic pet summon chances are slim, using ODIN Diamonds for higher-tier pet summon packs or direct purchases gives you a much better shot at completing this achievement without relying purely on RNG.

3. Glory in the Arena – Reach Top 100 in PvP Rankings

Reaching the top 100 in the PvP arena is tough and competitive. To stay ahead, many players enhance their gear and consumables using premium currency. Whether it's re-rolling stats, boosting enhancements, or acquiring PvP-specific gear sets, ODIN Diamonds play a key role in maintaining a competitive edge.

4. Guild Champion – Max Out Guild Contribution Points

Guild contribution points are earned through participation in raids, donations, and events. But let’s be honest: some days, you don’t have time to grind. This is where buying ODIN Diamonds can help—you can use them to quickly donate premium items or resources, speeding up your progress toward this achievement.

5. Legendary Hunter – Defeat 100 World Bosses

World Bosses spawn at specific times and drop top-tier loot, but competition is fierce. Securing buffs, teleport scrolls, and even consumables with ODIN Diamonds allows you to be better prepared and more efficient in your runs, which helps in reaching the 100-boss milestone faster.

6. Treasure Collector – Open 200 Premium Chests

Premium chests often require Diamond keys or are purchased outright with ODIN Diamonds. These chests contain rare materials, mounts, or accessories. Opening 200 of them isn’t something most players do casually, but if you’re planning to buy ODIN Diamonds, this is one of the more satisfying achievements to aim for due to the sheer amount of loot you’ll gather along the way.

7. Mount Master – Unlock 20 Unique Mounts

Mounts in ODIN Valhalla Rising aren’t just cosmetic; they impact movement speed and sometimes come with stat boosts. While some mounts are rewards from events, many are available through Diamond-exclusive packs. Carefully using your ODIN Diamonds to unlock mount bundles or special offers can bring you closer to this prestigious achievement.

While achievements may seem like optional side goals, they often come with valuable rewards such as titles, rare items, and even bonus stats. If you’re a completionist or just someone who enjoys unlocking everything the game has to offer, investing your time—and occasionally your ODIN Diamonds—into these rare achievements is a rewarding way to experience ODIN Valhalla Rising more deeply.
