Last Epoch Item Filter Generator

This skill helps generate Last Epoch stash search filters and lookup items.

Two Filter Systems

1. In-Game Loot Filter (Official)

• GUI-based, accessed via Shift+F
• Visual rule builder (no code/regex)
• Conditions: affixes, tiers, LP, rarity, class, level
• 75 rules max, top-to-bottom priority

2. Stash Search Syntax (This Guide)

Community-developed regex-like DSL for searching stash/databases. Used by Maxroll, lastepochtools.com, and checkmatez.github.io/eternity

Not official documentation - community convention.

Stash Search Operators

Core Syntax

• /pattern/ - regex text match
• & - AND operator (outside regex)
• | - OR operator (inside regex patterns)

Affix Modifiers

• 2T7 - exactly two T7 affixes
• 2T6+ - two or more T6+ affixes
• 3T5- - three or fewer T5 affixes
• sealed0 - no sealed affixes
• FP0 / FP1+ - forging potential
• prefixes1- - max 1 prefix
• suffixes1- - max 1 suffix

Item Modifiers

• LP1+ - legendary potential 1 or higher
• LP2- - LP 2 or lower
• exalted - rarity filter
• unique - unique items

Range Patterns

Use regex ranges for numeric values:

• [2-3][0-9] = 20-39
• 1[5-9] = 15-19
• [4-9] = 4-9

Complex Boolean Logic (A AND (B OR C))

Use | inside regex patterns for OR logic:

# Boots with 25-30% movement speed
FP1+&/boots/&/2[5-9]% increased movement|3[0]% increased movement/

# Pattern breakdown:
# A = FP1+&/boots/
# (B OR C) = /2[5-9]% increased movement|3[0]% increased movement/

Key rules:

• & joins conditions (AND)
• | inside /pattern/ creates alternation (OR)
• No parentheses grouping support
• Must repeat full pattern on each side of | including % and text

Common Filter Templates

Unique Items

/item name/&/[min-max]% stat/&LP1+

Exalted Craft Bases

/base type/&2T6+&sealed0&exalted

Slam Targets (2LP)

2T6+&sealed0&exalted&/desired affix/&/base type/

Item Databases

Maxroll

Syntax Origins

This DSL is community-developed, not official EHG documentation.

History:

• Patch 1.2.3: Added regex to in-game stash search
• Community tools extended this to create unified search syntax
• Conventions spread via Maxroll filters, forums, and tools

Key Tools:

• https://checkmatez.github.io/eternity/search/ - Filter builder
  • It's got some bugs but good for learning syntax
  • doesn't correctly generate some complex filters like percent greater than 25% logic
• lastepochtools.com - Database with search
• Maxroll filters - Popular presets

Workflow

1. Identify item and key stats
2. Find stat ranges from databases or in-game
3. Create stash search with regex ranges for thresholds
4. Add LP/tier requirements
5. Use in stash search or community tools
