Core Mechanics
Cursed Altars and Rituals
Cursed Altars generate randomly in the Overworld. Right-clicking one applies a random curse, ranging from minor annoyances to lethal effects. Each curse starts a ritual with specific conditions. Fulfill them to open a portal back to the altar, claim loot, and receive a gem—Broken, Polished, or Perfect. Rarely, the most difficult altars drop an Ancient Gem with game-changing properties. After a ritual, the altar enters a dormant state and can be used as a fusion table: combine three identical gems to upgrade them (three Broken become one Polished, three Polished become one Perfect). Ancient Gems cannot be crafted this way.
Gem Types and Progression
Gems are divided into four tiers. Each gem has a primary and secondary slot; bonuses are higher in the primary slot.
- Minor Gems (Broken): Amethyst (+2 HP), Diamond (+1 armor), Emerald (+0.25 luck), Ruby (+0.5 damage), Sapphire (+10% magical amplification), Topaz (+7.5% speed). Fit only into minor slots.
- Polished Gems: Double the minor bonuses in secondary slots, quadruple in primary slots. Universal slot compatibility.
- Perfect Gems (Major): Massive stat boosts plus a unique effect when placed in a primary slot. Amethyst grants Lifebloom (auto-heal below 50% HP), Diamond gives Hardening (20% chance to ignore damage for 3s on block/hit), Emerald offers Fortune's Favor (chance to double drops), Ruby triggers Critical Fury (crits boost all damage by 25% for 5s), Sapphire provides Arcane Amplification (randomly raises enchantment levels by 1–2), and Topaz enables Frenzied Blows (melee hits stack up to 15% attack/move speed).
- Ancient Gems: Extremely rare, primary slot only. Alexandrite shifts between Twilight's Edge (night vision, undead bonus, dodge) and Dawn's Light (daytime damage boost, sun regen). Bismuth cycles elemental auras and bursts. Chrysoberyl grants creative flight, +50% attack/move speed, and +3 luck.
Amulet and Lapidary Table
Craft a Golden Amulet with 3 string, 2 gold nuggets, and 1 gold ingot. It is useless alone, but on a Lapidary Table you can socket gems into it to gain health, attack, armor, luck, and magical amplification. Armor can also be inlaid: combine a diamond with an armor piece on an anvil to create a socket, then use the Lapidary Table to insert a gem. Armor sockets work like the amulet, except Major gem effects are disabled.
Magical Amplification
This stat extends positive potion durations and sometimes strengthens their effects. High amplification makes regeneration last significantly longer and tick faster, turning ordinary buffs into powerful survival tools.
Strategic Depth and Replayability
Ancient Curses: Mastering Cursed Altars and Gems rewards preparation and smart gem fusion. Start with minor altars to collect Broken gems, upgrade them to Perfect, and build an amulet that suits your playstyle. The mod respects vanilla balance while adding a fresh risk-reward loop. Every altar run is a self-contained story, and the rare Ancient Gems offer build-defining choices. Whether you seek flight, elemental chaos, or day/night duality, the mod delivers meaningful progression without bloating your game. Download it today and turn ancient curses into your greatest asset.
