Clue scrolls drop from monsters and come in four tiers: medium, hard, elite and master. Solving a clue is a journey across the world map: follow the trail to 2–4 waypoints, searching each one, and the final search grants the reward. Searching takes about 5 minutes total for medium, 15 for hard, 30 for elite and 60 for master, plus road time — teleporting between waypoints finishes the trail faster, and if you have another scroll of the same tier the next journey starts automatically. Rewards are 1 to 4 rolls from that tier's loot table: runes, coins, gear and rare uniques (like the 2nd Age sets) that fill your collection log. Higher tiers roll rarer rewards.
