Arcanum - Custom Enchantments v0.3.0

Arcanum v0.3.0 is a big content update — new ways to earn enchants, a brand-new rarity, and structures to hunt for. Fully backward-compatible; just swap in the new jar.
New ways to get enchants

• Mob Drops — hostile mobs now have a small, balanced chance to drop a random enchantment book. Tougher mobs and Looting improve the odds; bosses drop generously. Anti-farm built in (player kills only, no spawner mobs).
• The Enchanter — a new menu inside /enchants: spend XP levels to buy a random enchant book of the rarity you choose.

New "Secret" rarity (above Mythic) — 3 exclusive enchants:

• Oblivion (weapon) — chance to strike with lightning + an explosion for huge bonus damage.
• Immortal (chestplate) — cheat death and heal to full (cooldown).
• Voidwalker (boots) — permanent Speed & Jump, negates fall damage, and saves you from the void.

Arcane Vaults — rare generated structures, found on the surface AND hidden underground, each holding a guaranteed Secret enchant book plus bonus loot. The only way to obtain Secret enchants.
Quality of life

• The catalogue now shows the per-kill drop chance on every rarity and enchant.
• Everything's configurable: drop rates, structure frequency, underground ratio, Enchanter costs, and more.

Now 46 enchants across 7 rarity tiers.
