 * The Frozen Dungeon equipment (James's sheet, 2026-09-22): a set forged in

 * it. It comes three ways, one piece at a time:
 *
 *  - a Frozen Depths boss kill rolls ONE chance at ONE piece
 *    (FROZEN_SET_BOSS_DROP_CHANCE, the Behemoth's 5% the best);
 *  - the Frozen Chest in the Frozen Shrine, opened with a Frozen Chest Key
 *    (a 0.1% drop from anything that lives in the frost dungeon, 2% from a
 *    boss), rolls the set at FROZEN_CHEST_ROLL_CHANCE;
 *  - the Frozen Key that opens the Hallway (woodwork.ts FROZEN_KEY_KIND,
 *    fished up one drop in a thousand) also drops from those same NPCs.
