In Valheim, rare item drops (such as trophies and rare materials) utilize an internal pseudo-random countdown (s_pseudoCounter) to guarantee drops after a set number of kills.

In Patch 1.0.20, Iron Gate added basic character persistence for this dictionary and attempted to scale trophy drop rates with monster stars. However, their implementation introduced severe mechanical flaws: pity counters are split across star tiers, 2-star enemies are excluded from pity entirely, and the static dictionary leaks across characters on the character select screen.

SaveYourLuckBruh fixes these issues by unifying pity progression across all star tiers, isolating character saves from menu preview leaks, preserving per-world progression, and protecting your pity counters in co-op.

🎯 The Problem with Vanilla 1.0.20

In Patch 1.0.20, Iron Gate made two major changes to CharacterDrop:

1. They serialized CharacterDrop.s_pseudoCounter into the .fch character save file.
2. They allowed monster star levels to multiply trophy drop chances.

While this addressed the basic issue of counters resetting on logout, their implementation created three critical problems:

1. Star-Level Pity Fragmentation

Iron Gate changed the dictionary key to a compound hash: hash(prefabName) + (chance * 1000). Because chance scales with star level (0-star = 10%, 1-star = 20%, 2-star = 40%):

• A 0-star Cultist and a 1-star Cultist write to completely different dictionary entries.
• Kills on 0-star and 1-star enemies do not pool together. If you kill 8 0-stars and 2 1-stars, neither counter advances the other.
• Because 2-star Cultists have a 40% drop chance, they exceed vanilla's 30% cutoff (chance <= 0.3f). 2-star enemies are completely disqualified from pseudo drops. They do not advance pity, and if a 2-star drops a trophy, your 0-star counter does not reset—giving you an unintended duplicate drop shortly after.

2. Static Memory Leak / Cross-Character Pollution

CharacterDrop.s_pseudoCounter is a static dictionary. In Player.Load, vanilla inserts saved entries without ever calling .Clear(). Because Player.Load is executed during character preview in the main menu, cycling through characters on the start screen merges all their counters together into memory. Whichever character you launch into the world inherits the combined counters of every previewed character.

3. Multiplayer ZDO Attribution & World Bleed

Only the network owner of a creature's ZNetView executes drop calculations. In co-op, an ally landing a kill can consume your personal countdown. Furthermore, vanilla counters are tied globally to the character file with zero world scoping, allowing players to farm pity in local worlds and cash it in on multiplayer servers.
