Master Coordinates

A coordinate clue contains a set of numbers which point to a specific location where the next clue (or casket) will be found.

A chart and sextant is required to determine your current location and a spade will be needed to dig at your final location.

Master Treasure Trails will cause either three Ancient Wizards (levels 112, 98, and 98) or a level 140 Brassican Mage to spawn depending on the combat zone of the coordinates (multi or single). The three Ancient Wizards attack which melee, range, and magic — respectively. Melee wizards are also poisonous.
