LevelingSystem: Skills & Nearby XP

A cooperative progression mod for Valheim, maintained by DelooLV and based on the work of Thrakal (Cozyheim) and DeepWolf413.

Highlights

• Shared creature-kill XP for every living player inside the configurable nearby radius.
• Ten skills with persistent ranks, refunds, server-synced balance settings, Russian and English localization.
• A restored Nordic skills menu, smooth XP bar, floating XP, level-up, critical-hit and summon-hit effects.
• Multiplayer-safe skill ranks synchronized through player ZDO data.
• Configurable rested-XP multiplier, skill points per level, maximum ranks and bonuses per rank.

Skills

Press I by default to open the skills menu. The key and every balance value can be changed in the synchronized BepInEx configuration.

Modded summon compatibility

The mod automatically recognizes creatures that use Valheim's standard Tameable / MonsterAI command-and-follow ownership. This covers vanilla summons and many modded creatures.

Mods with a custom ownership system can integrate without a hard dependency:

SummonOwnerResolver.RegisterResolver(character =>
{
    // Return the owning Player, or null when this character is not your summon.
    return TryGetOwnerFromYourMod(character);
});

Damage effects are applied through normal HitData, so projectile and melee attacks from compatible modded summons are supported.

Server/host commands

• set_level <playerName|me> <level>
• level_up <playerName|me> <amount>

Requirements

• BepInExPack Valheim 5.4.2333 or newer compatible release
• Jötunn 2.29.2
• JsonDotNET 13.0.3

The mod is required on every client and the server. Back up character saves before upgrading from an older progression build.

v0.6.0 (latest)

Important! This is a big update, I reworked several parts of the mod with significant changes to how they work. Please do a backup before updating.

• Reworked configs
  • All default configs are now embedded into the mod itself - it is not intended for them to be editable. The mod can always fallback to a default config in case something goes wrong loading custom configs.
  • Installing the mod on a dedicated server will no longer require manually, moving the default configs to make sure the mod is functioning properly. Like mentioned earlier, they are now embedded into the mod itself.
• Project clean-up
  • Improvements to the project structure will make it easier to debug and fix bugs from now on.
• New integrations
  • CLLC (CreatureLevelAndLootControl)
• Removed integrations
  • DifficultyScaler
    • Removed as I'm not maintaining it anymore, and there are mods that does the same better.

v0.5.19 (Latest)

• Adds more error messages to xp config loading process.
  • A warning will be written to the console if it failed to read a xp config file, including the reason it failed to load. The mod will continue to run, as long as one of each xp type config was able to loaded.
    Likely causes for failing to load are: invalid JSON structure, and comments.
• Fixes an issue with the inability to add/remove skill points from some skills. The interact text would partially block some of the skill buttons with its big hitbox.
• Removes embedded third-party libraries that are no longer needed.

That was all for this patch. I am still working on a major update that will significantly improve all aspects of the mod, such as, the stability, ease of use, UI rework to be consistent with the game, more customizability, and much more.
