Turn every adventure into character growth. Sol's Leveling System is a Minecraft RPG leveling mod built around Player Levels, five build-defining Aptitudes, 25 ranked Aptitude Passives, three use-based Combat Masteries, and 18 automatic Mastery Passives.
Fight dangerous creatures, stay active in hostile territory, specialize your stats, and master the combat styles you actually use. The system is designed for both vanilla and modded adventures: stronger enemies are worth more, repeated farms lose value, and final effective damage—not overkill—drives mastery progress.

Press Y while playing to open the Leveling Screen. This is the default keybind on every supported edition.
You can also open your inventory and click the Open Leveling crest beside it. If another mod already uses Y, change Open Leveling Screen in Minecraft's Controls menu under Sol's Leveling System.
The Leveling Screen contains your Player Level and EXP progress, available Aptitude Points, stat previews, Aptitude allocation, ranked Passives, Combat Masteries, recent EXP sources, and confirmation prompts.

Every Aptitude grants a direct stat benefit and unlocks its own passive tree:
Unused Aptitude Points can be spent freely. Reclaiming confirmed ranks costs raw Minecraft Experience points and is blocked briefly after combat, so builds can evolve without making choices meaningless. Aptitude passive ranks cost no points: once both requirements are met, claim them in the passive tree. Every passive can be toggled individually.

Combat Masteries grow from final, effective hostile health removed:
Hover a supported item to see how the server classifies it. Each attack contributes to at most one Mastery, and overkill or healed-back health cannot create extra Mastery EXP.
Hostile mob EXP is calculated from a spawn-time snapshot of health, defenses, attack power, movement, encounter difficulty, boss status, spawn origin, and repetition. Damage contributors share the reward fairly, while the final hitter remains eligible. Spawner-born and repeated creatures are reduced by default.
Active Survival provides a small alternative source of Player EXP every five eligible minutes. It rewards players who remain active and recently face danger; AFK time does not count, and death or combat logging resets the streak.

At Fortune 50, Limit Breaker turns a desperate boss, elite, or PvP encounter into a timed wager. After one worthy enemy deals cumulative damage equal to 30% of your Max HP, a nonlethal hit that leaves you at 30% HP or lower can offer All In.
Hold Sneak to accept. You return to full health, gain a shield, speed, offense, and damage reduction, then race to defeat the marked Limit. Victory grants recovery, bonus progression, and eligible bonus loot. Failure causes Limit Crash: reduced damage, speed, healing, and Luck effects for a level-scaled duration.
Sol's Leveling System must be installed on both the server and each connecting client. It has no required content-mod dependency.
