In Odin: Valhalla Rising, character progression is about far more than leveling up or equipping the strongest gear. Beneath the surface lies a deep system that rewards exploration, grinding, and long-term planning: the Item Collection system. This feature allows players to permanently boost their character’s stats by registering specific items obtained from monster hunting, dungeons, Odin Diamonds, and various in-game activities.

Unlike consumable buffs or temporary enhancements, Item Collections provide lasting bonuses that accumulate over time. Whether you are a casual adventurer or a hardcore min-maxer, mastering this system can significantly improve your performance in PvE and PvP alike.

This guide walks you through everything you need to know about the Item Collection system—how to add items, how the “Add All” feature works, how to use Brokkr Universal Keys, how to filter and search collections efficiently, and how to hide categories you don’t want cluttering your interface.

Understanding the Item Collection System

The Item Collection system is designed to reward players for acquiring and sacrificing specific items. When all required materials for a collection are added, the collection activates and grants extra stats such as Attack, Defense, HP, Accuracy, Evasion, and other combat-related bonuses.

These bonuses apply automatically once the collection is complete and do not require the items to remain in your inventory. Once added, the items are permanently consumed for collection purposes.

The key idea behind this system is progression through accumulation. Every dungeon run, monster hunt, or rare drop contributes not only to your immediate power but also to your long-term character growth.

1. How to Add Items to Collections

Accessing the Item Collection Menu

To begin adding items:

Tap the menu (☰) icon located in the top-right corner of the screen.

Select “Item Collection” from the menu to enter the collection interface.

Once inside, you’ll see multiple tabs divided by categories such as Attack, Defense, Debuff, and others. Each tab contains a list of collections that can be completed by adding specific items.

Identifying Addable Items

Items that can be added to a collection are clearly marked to help you identify them quickly:

Addable items are highlighted and display a red dot notification.

Selecting an item shows a tooltip with detailed information and an “Add” button.

This visual system makes it easy to spot which items in your inventory are eligible for collection progress without needing to cross-reference manually.

Adding an Item Step-by-Step

Select an item marked with a red dot.

Click “Add” in the tooltip.

Confirm your selection by clicking “Add” and then “OK” in the pop-up window.

Once confirmed, the item is registered as part of the collection.

Important: Collection effects only activate after all required materials for that collection are added. Partial progress does not grant partial bonuses.

The “Add All” Feature – Faster Collection Management

As your inventory grows, manually adding items one by one can become time-consuming. Odin: Valhalla Rising addresses this with the extremely useful Add All feature.

How to Use Add All

Click the “Add All” button located in the middle-bottom of the Items screen.

The Add All option will open with configurable filters.

You can set conditions such as:

Item grade

Item type

Collection category (e.g., Attack, Defense, Debuff)

Once the filter is applied, all items that meet the selected conditions are automatically highlighted.

Fine-Tuning Your Selection

You can manually select or deselect any addable item by tapping it in the Add All screen.

Selected items are marked with a yellow square-shaped outline, making them easy to identify.

Locked items are automatically excluded and cannot be selected.

When ready:

Click the “Add” button to register all selected items into their respective collections at once.

Add All Rules and Limitations

There are a few important details to keep in mind:

The Add All feature works individually per tab (Attack, Defense, Debuff, etc.).

If you have fewer items than required, the system prioritizes selection in ascending order, moving left to right within the collection list.

Items must be addable and unlocked to be included.

Used correctly, Add All can save a massive amount of time, especially during long farming sessions.

Searching for Items in Collections

As your collection list expands, finding specific items becomes increasingly difficult. The Search Item function solves this problem.

How Search Works

Enter the item’s name into the search bar at the top of the Item Collection screen.

The system displays relevant collection entries that require that item as a material.

Each category shows its required collection list, although some items may not currently be addable depending on your inventory.

Advanced Search Behavior

Selecting an item from the search results will filter the screen to show only collection items that use it as a required material.

To return to the full collection view, click the Reset button in the top-right corner.

This feature is invaluable when you acquire a rare item and want to immediately see where it can be used.

Favorites for Faster Access

Next to each collection entry, you’ll see a star icon.

Clicking the star adds the collection to your Favorites tab.

Favorites allow you to track high-priority collections without scrolling through every category.

This is especially useful for long-term goals or rare equipment-based collections.

2. Brokkr Universal Keys – Substituting Missing Equipment

One of the most powerful and flexible tools in the Item Collection system is the Brokkr Universal Key. This item allows you to substitute missing equipment pieces, helping you complete collections even if you haven’t acquired every required drop.

What Is a Brokkr Universal Key?

The Brokkr Universal Key acts as a replacement material for certain equipment items in a collection.

Key rules include:

The key’s grade must match the grade of the equipment item being substituted.

The number of keys required depends on the equipment’s type and enhancement level.

This system reduces frustration caused by bad RNG and allows steady progress toward stat bonuses.

Eligible Items for Substitution

Not all items can be replaced using Brokkr Universal Keys. Substitution is limited to:

Weapons and Armor (up to +7 enhancement)

Cloaks and Accessories (up to +3 enhancement)

The following items cannot be substituted:

Relics

Event items

Other non-equipment collectibles

How to Use the Substitute Feature

Select an incomplete collection item.

Tap the required material to open its tooltip.

Click the [Substitute] button.

The required material will be converted into a Brokkr Universal Key equivalent.

Click [Add] to finalize the substitution and save it as part of the collection.

Important Substitution Notes

The [Add] button will be disabled if you do not possess a suitable Brokkr Universal Key.

Pressing [Substitute] again will revert the material back to the original required item.

Substitution only affects the collection and does not provide the actual equipment item.

Used wisely, Brokkr Universal Keys allow you to complete high-value collections without endlessly farming specific drops.

3. Filter Settings – Customizing Your Collection View

With dozens of collections available, the interface can quickly become overwhelming. The Filter Settings feature helps you display only what matters most.

How to Set Filters

Click the “Filter Settings” button in the bottom-left corner of the Item Collection tab.

Adjust your desired conditions:

Status

Item type

Item grade

Options

Click OK to apply the filters.

The collection list will immediately update to match your preferences.

Filter Behavior and Resetting

Filters apply individually to each collection category.

You can reset filters at any time by clicking “Reset Search” in the top-right corner.

If you select [Status] – [Hide], hidden collections will also appear in the filtered results, giving you full control over what is displayed.

4. Hiding Items and Categories

For players who prefer a clean interface, the Hide function allows you to minimize clutter.

How Hiding Works

Tapping the Hide icon will minimize a collection category.

Hidden categories will not trigger pop-ups when you acquire relevant items.

Hidden items are excluded from collectible counts shown in the Bag UI tooltip.

This feature is perfect for collections you plan to complete later or categories that are irrelevant to your current build.

Final Thoughts: Why Item Collections Matter

The Item Collection system in Odin: Valhalla Rising is one of the most underrated yet impactful progression mechanics in the game. It rewards dedication, smart inventory management, and strategic use of systems like Add All and Brokkr Universal Keys, cheap Odin Diamonds.

Over time, the cumulative stat bonuses from collections can rival or even surpass gear upgrades, making this system essential for players who want to push endgame content or compete at higher levels.

By learning how to efficiently add items, filter collections, substitute missing equipment, and organize your interface, you transform routine farming into meaningful long-term growth. If you’re serious about maximizing your character’s potential in Odin: Valhalla Rising, mastering the Item Collection system is not optional—it’s essential.
