In Path of Exile 2 (POE 2), one of the most crucial elements of gameplay is managing the vast amount of loot that drops during your journey. With the game's high item density and ever-expanding content, players can quickly become overwhelmed by the sheer number of items that clutter their screen. To address this, loot filters were introduced, allowing players to highlight specific items of interest and streamline their gameplay experience. However, as players become more experienced, they begin to crave further customization to their loot filters, especially in the context of currency management. This is where advanced regex (regular expressions) rules come into play, offering players an efficient and powerful tool for fine-tuning their loot filters. In this blog post, we will explore how advanced regex rules can be used to optimize currency loot filters in POE 2, helping players focus on the most valuable items without being distracted by the rest.

Understanding Loot Filters and Regex in POE 2

Loot filters in POE 2 are essential tools that allow players to define what items they want to see during their gameplay. These filters can be customized to highlight specific types of items, such as rare currencies, gems, or unique equipment, while hiding everything else that is deemed unnecessary or less valuable. Loot filters are particularly beneficial for players who engage in currency farming or trading, as they can be adjusted to show high-value items like Exalted Orbs, Chaos Orbs, or other coveted currencies.

While basic loot filters can highlight these items with simple settings, more advanced players often turn to regex for finer control. Regular expressions are a powerful tool for pattern matching within text, allowing players to create more sophisticated rules for loot filtering. Regex can be used to match item names, affixes, or modifiers based on specific patterns, offering unparalleled flexibility and precision in filtering loot.

Setting Up Advanced Regex Rules for Currency

When setting up advanced regex rules for currency loot filters in POE 2, players can target very specific currency items or patterns within those items. For example, if you want to highlight every Orb of Chaos drop, you can create a regex rule that matches the exact name of the item. But regex goes beyond simple name matching—it can also match specific item mods, rarity, or item types, which are all critical for managing large volumes of currency items.

To get started, here are some fundamental regex components to understand:

Literal Matching
The most basic regex rule is literal matching, where you specify the exact name of an item or currency. For example, to match "Exalted Orb," you can use the regex pattern This rule will ensure that the filter highlights only this specific currency drop.

Wildcards and Modifiers
Regex also supports wildcards and modifiers, making it possible to create patterns that match multiple variations of a currency item. The period (.) wildcard, for instance, can match any character, and the asterisk (*) allows for repetition. For example, the regex would match any currency item that starts with "Orb" and ends with "Chaos," thus capturing all types of Orbs related to Chaos, such as Orb of Chaos, Orb of Scouring, and so on.

Character Classes
Regex allows you to define sets of characters that can be matched at a given position. For example, matches any alphabetical character, while \d matches any digit. By combining these character classes, you can create more complex matching patterns. For instance, would match any Orb with a numeric value followed by "Chaos," useful for filtering currency with a specific modifier or value.

Anchors and Boundaries
Anchors like (start of a line) and $nd of a line) can help you match items at the beginning or end of a string. For instance, would only match the exact phrase "Orb of Chaos," excluding any extra words or modifiers that may appear in the item's name.

Practical Examples for poe2 currency Loot Filters

Now that we understand some of the fundamental regex components, let's explore some practical examples for currency loot filters in POE 2.

Highlighting Specific Currency Types
If you want to filter out all items except for high-value currencies, such as Exalted Orbs and Divine Orbs, you could use a regex pattern like this:

This rule will ensure that only Exalted Orbs and Divine Orbs are highlighted, while other currencies will be ignored.

Filtering by Currency Prefix or Suffix
In POE 2, currency items may have prefixes or suffixes that indicate their value or quality. For instance, if you're looking for Orbs with the prefix "Stacked Deck," you can use the following pattern:

This will match any Orb that contains "Stacked Deck" in its name, filtering out other less valuable currencies.

Excluding Low-Value Currency Drops
For players focused on farming high-value currencies, it may be helpful to exclude lower-tier currencies like Alteration Orbs or Transmutation Orbs from your loot filter. A regex rule like this can accomplish that:

This rule ensures that any item containing "Alteration Orb" or "Transmutation Orb" will be excluded from the loot filter.

Matching Currency with Specific Item Mods
In addition to item names, regex can also be used to match specific item modifiers that are typically associated with high-value currency items. For example, if you want to highlight currencies with the modifier "increased item rarity," you could use a pattern like:

This would match any currency item with that specific mod, helping players target items with valuable additional properties.

Advanced Tips for Efficient Loot Filtering

While regex is a powerful tool, it’s essential to balance complexity with efficiency when setting up your loot filters. Here are some advanced tips for making the most of your regex rules:

Test Your Regex Patterns
Before implementing your regex rules in the game, it’s a good idea to test them in a regex testing tool. This will help ensure that your patterns work as expected and don’t unintentionally match unwanted items.

Keep It Simple
While it’s tempting to create highly complex regex rules, it’s important to keep your loot filter as efficient as possible. Overcomplicating your rules can lead to performance issues, especially in high-density areas. Stick to the most critical patterns that align with your currency goals.

Regularly Update Your Filter
The POE 2 economy is constantly evolving, and so should your loot filter. As new currency items or valuable mods are introduced, make sure to update your regex patterns to reflect these changes. Regular updates will keep your filter relevant and efficient.

Advanced regex rules are a game-changer for currency loot filtering in POE 2. They allow players to fine-tune their loot filters, ensuring that only the most valuable currency items appear on their screens. By mastering regex, players can greatly enhance their currency farming experience, focusing their efforts on the most profitable drops and avoiding unnecessary clutter. Whether you’re a casual player or a seasoned veteran, utilizing advanced regex in your loot filter is an essential step towards optimizing your POE 2 gameplay.
