How the Lost Loot System Works

Automatic Collection Mechanics:

Chest loot monitoring – Tracks items you’ve seen but not collected
Ground drop detection – Captures items dropped by enemies or players
Cliff edge protection – Recovers loot that falls into unreachable areas
Inventory overflow assistance – Collects items when your backpack is full

Manual Management Required:

The Lost Loot system operates passively but requires active player maintenance:

Visit machines regularly to prevent capacity overflow
Clear contents manually – no automatic sorting or deletion
Monitor capacity – full machines stop collecting new items
Strategic timing – empty before high-value farming sessions

Critical Limitation: No Filtering System

The Lost Loot machine cannot discriminate between item rarities or types:

No legendary-only collection settings available
No item type filtering (weapons, shields, etc.)
First-come-first-served slot allocation
Common items can block legendary drops if capacity is full

This limitation makes regular maintenance crucial, especially before engaging in legendary farming activities.

Storage Capacity and SDU Upgrades

Base Capacity:

The Lost Loot machine starts with limited storage slots, making upgrades essential for serious players.

Maximum Upgrade Potential:

14 total slots when fully upgraded with SDU Tokens
Significant investment in SDU Tokens required
Permanent character improvement across all playthroughs
Essential for endgame farming efficiency

SDU Token Investment Strategy:

Consider Lost Loot upgrades alongside other storage improvements:

Weapon inventory expansion (highest priority)
Ammo capacity increases for sustained combat
Lost Loot storage for farming safety net
General inventory space for exploration

Strategic Usage and Best Practices

Pre-Farming Preparation:

Essential Steps Before Major Farming Sessions:

Empty all nearby Lost Loot machines to maximize capacity

Regular Maintenance Schedule:

Optimal Management Frequency:

After each major boss farming session to clear accumulated items
Before entering new regions to ensure capacity for exploration

Check for legendary items first and secure immediately
Mark lower-tier items as junk for efficient selling
Bank valuable situational items you don’t need currently

Integration with Inventory Management

Complementary Systems:

The Lost Loot machine works best when combined with other inventory management tools:

Banking Strategy:

Store long-term valuable items in bank storage
Keep Lost Loot clear for active collection
Rotate equipment based on current needs

Junk System Utilization:

Mark unwanted Lost Loot items as junk immediately
Use “Sell All Junk” feature at nearby vendors
Clear machine efficiently without individual item evaluation
