Combat only pure/Treasure Trails/Guide/Coordinates/Hard

During a Treasure Trail, a coordinate clue is a clue scroll that contains a set of coordinates. These coordinates indicate a precise point somewhere on the surface where the next clue scroll or treasure casket is buired.

Coordinates are presented in the following format:

03 degrees 00 minutes north/south
02 degrees 00 minutes east/west

In Old School RuneScape, one square of space is equivalent to 15/8 (1.875) minutes of arc. 0°00' degrees north and 0°00' degrees east is located in the middle of the Observatory.

A chart, sextant and watch may be used to determine one's present coordinates, but if using a guide to find the coordinates, players will only require a spade to dig up the clue.

On hard Treasure Trails, digging on the correct spot will cause a hostile level 108 Saradomin wizard to appear when outside of the Wilderness, otherwise the level 65 Zamorak wizard will appear. These wizards must be defeated in order to dig again to retrieve the clue scroll or treasure casket.

The Saradomin wizard will immediately attack the player with a poisoned dragon dagger. They will change attack styles between Melee and Magic to counter protection prayers if activated within melee distance. Keeping distance while praying Protect from Magic will cause them to attack only with Magic, allowing the player to negate all damage. The player may choose to pray Protect from Melee to prevent the poison on the first hit, then switch to Protect from Magic once at a distance. Alternatively, an antipoison may be used.

The Zamorak wizard will immediately attack the player with the Flames of Zamorak spell. Unlike their Saradomin wizard counterparts, they attack exclusively with Magic, do not deal poison and all damage can be negated with Protect from Magic. They are also generally weaker, having low Hitpoints and low Defence (except against Magic).

On elite Treasure Trails, digging on the correct spot will cause either a level 97 Armadylean guard or a level 125 Bandosian guard to appear, which must be defeated before the next clue scroll or the treasure casket may be dug up. Armadylean guards must be killed with either Ranged or Magic attacks, since they are in the form of an Aviansie. It is advised to use the Protect from Missiles prayer when fighting them, and Protect from Melee when fighting Bandosian guards.

On master Treasure Trails, digging in the correct spot will cause either three Ancient Wizards (levels 112, 98, 98) in multi-combat to appear, or a level 140 Brassican Mage, which need to be defeated before the next clue scroll or the treasure casket may be dug up. If the coordinates are located in a multi-combat area, three Ancient wizards, each attacking with a unique attack style, will appear. Melee wizards are poisonous, with poison dealing 8 damage to a player. In single-combat zones, a Brassican Mage will appear, and its attacks cannot be stopped by protection prayers.

Following is a list of all known coordinate clues and their corresponding locations. The list is organised into ascending numerical value (for example, 00:00 north first, then 00:05 south, then 00:13 north, continuing accordingly). Shorthand writing is used together with normal writing. An example: 09°34'N, 25°12'E = 09 degrees and 34 minutes north, 25 degrees and 12 minutes east. • Remember: You must have a spade with you to dig up coordinate clues.

Note that some of the clues may require skill or quest requirements before you will be able to get to that location.' These quests, which must be finished or partially completed, include: Bone Voyage, Regicide, Legends' Quest, Nature Spirit, The Grand Tree, Fairytale II - Cure a Queen, Troll Stronghold, Cabin Fever, The Fremennik Trials, and Watchtower. Some coordinates will also require a certain skill levels to complete the clue, though the required level is low.
