In ODIN Valhalla Rising, timed events often come with exclusive rewards that can give your account a major boost. But if you’re just participating on the surface, chances are you’re missing out on hidden or bonus rewards tucked behind event mechanics. As someone who's spent a good chunk of time experimenting with event systems and testing reward triggers, I’ve found several ways to reliably unlock these extras — especially when ODIN Diamonds are part of the equation.

Here are 8 strategies to help you trigger bonus rewards during events, whether you're a veteran spender or looking to get more value from your stash of cheap ODIN Diamonds.

1. Complete Daily Event Missions Consecutively

Many events include daily missions, but completing them on consecutive days can trigger additional milestone rewards. These bonuses often don’t appear in the UI until you’ve hit the streak threshold, so consistency pays off. Don’t skip a day, even if the tasks seem minor.

2. Spend ODIN Diamonds Within Specific Timeframes

Certain event windows reward players for spending ODIN Diamonds during peak activity hours — usually reset times or special "boost periods." Watch for system announcements or in-game mail hinting at these windows. Even small purchases made during these times can unlock hidden caches or multipliers on points.

3. Upgrade Event-Linked Gear or Costumes

Events tied to special gear or cosmetics sometimes have hidden progression rewards. For example, enhancing a specific costume or weapon during a festival event can trigger bonus gifts. While these bonuses aren’t always advertised, they frequently include rare materials or currency packs.

4. Participate in All Event Modes (Even the Niche Ones)

Don’t just grind the main boss raid or leaderboard. Some of the best hidden rewards come from participating in underused event modes — like exploration mini-games, timed dungeons, or PvP training arenas. Event achievement trackers often require at least one completion across every mode to unlock final-tier rewards.

5. Combine Diamond Spending With Guild Activities

Events that overlap with guild contribution mechanics can offer layered benefits. For example, using ODIN Diamonds to boost guild research or unlock shared bonuses during an event week may reward you with both personal and guild-level bonus chests. This synergy is often missed by solo-focused players.

6. Hit Purchase Milestones With Cheap ODIN Diamonds

If you're spending, consider breaking up your ODIN Diamonds purchases. Instead of a single bulk transaction, make smaller buys at specific thresholds (like 500, 1000, 2000 Diamonds). These often correspond to hidden milestone bonuses in event reward charts. Using cheap ODIN Diamonds during discount windows is a smart way to maximize your return.

7. Interact with Limited-Time Event NPCs Multiple Times

Event NPCs may change dialogue or available quests as the event progresses. Visit them daily — not just once. Some players have triggered secret quests or reward chains by interacting with the same NPC on multiple days or after reaching specific in-game progress milestones.

8. Achieve Top Ranks in Minor Leaderboards

While most players gun for the main rankings, secondary leaderboards — such as “Most Damage Dealt in One Attempt” or “Fastest Solo Clear” — sometimes offer hidden prizes. These aren’t always obvious from the main UI, but check mailboxes or achievement tabs after events end. Even a rank in the top 200 may net you extra Diamonds or enhancement scrolls.

Event rewards in ODIN Valhalla Rising aren’t just about showing up — they’re about engaging smartly with the systems that players often overlook. Whether you’re sitting on a stockpile of ODIN Diamonds or looking for ways to stretch your cheap ODIN Diamonds further, keeping an eye on timing, interaction, and hidden milestones will set you ahead.
