Superpower Gems

Gems

Overview

Gems is a PvP-first RPG progression mod built around gem archetypes. Each gem grants a unique set of passives and active abilities, unlocked through a level and energy system that rewards kills, punishes deaths, and creates constant power swings. Progress carries across swaps, so you can change playstyles without starting over.

Core Loop: Energy, Levels, and Unlocks

• You spawn with a random gem at 3 energy.
• Kills grant +1 energy and death removes -1 energy.
• Energy tiers: Broken (0) -> Common (1) -> Rare (2) -> Elite (3) -> Mythical (4) -> Legendary (5) -> Legendary +1 to +5 (6 to 10).
• Ability access scales with energy:
  • 0 to 1: passives and abilities disabled
  • 2 to 4: keep the first (energy - 1) abilities active
  • 5 plus: full kit online
• Leveling (max level 10):
  • Level 1: all passives
  • Levels 2 to 4: unlock abilities in gem-defined order
  • Level 5: unlock any remaining abilities
  • Levels 6 to 10: buffer levels (no new powers)

Hearts, Death, and the Assassin Endgame

• On death, players drop one Heart item that increases max health when consumed.
• Max health limits: cannot drop below 5 hearts and cannot exceed 20 total hearts.
• If you die while already at 5 max hearts, you become an Assassin:
  • Highlighted red in the player list and tab UI
  • Fixed 10-heart cap
  • Never drops hearts and cannot consume heart items
  • If killed by another Assassin: -2 max hearts
  • Can only regain those hearts by killing other Assassins
  • Reaching 0 max hearts permanently eliminates the Assassin
• Scoring (only after becoming an Assassin):
  • Normal kill: +1 point
  • Final kill (turning someone into an Assassin): +3 points
  • Winner selection uses points (admin-run duel afterwards): highest-score Assassin vs last surviving non-Assassin

Gem Swapping, Ownership, and Upgrades

• Gems are bound to their owner. You can own multiple gems, but only one is active.
• Gem Trader swaps only your active gem (owned gems stay owned).
• Gem Purchase Token lets you pick any gem to add to your owned set and activate.
• Craft Energy Upgrades to increase gem energy (up to Legendary +5).
• At Legendary +5, players gain an enchant glint. If a Legendary +5 player kills a non-broken player, the victim drops an upgrade item that anyone can consume for a level (not usable by Legendary +5).

Legendary Items

Legendary items are unique, server-wide crafts designed to create objectives, conflict, and endgame moments.

• Each legendary craft takes 10 minutes.
• When crafting starts, the crafter’s location is announced globally.
• Crafting progress is shown to all players via a boss bar with coordinates.
• When complete, the item drops at the crafting table.
• Some recipes require a player head that is not your own.
