The Explorer's ring 2 is a reward from the beginner and easy Lumbridge and Draynor Tasks. The ring is received from Bob in Lumbridge, and can be retrieved from him for free if lost. The ring is one of the many items which are always kept on death, in addition to the standard three items (except if in the Wilderness).
The ring can be used in the Fist of Guthix minigame to recharge the wearer's run energy. This is helpful when they need to run or attack their opponent depending on their current role (hunter or hunted) in-game.
Players gain the normal experience for casting Low Level Alchemy with the ring (31 experience). Due to the fact that a nature rune is not required, the ring's Low Level Alchemy is more economical than casting High Level Alchemy on items with a high alch value of less than three times the current nature rune price (3*445 = 1,335). Some items can be purchased for less than the low alchemy value (e.g. Steel claws), thus generating a small profit from this.
The Great Orb Project is an excellent opportunity to gain extra runes using this ring, though level 50 Runecrafting is a requirement to get into the guild.
The ring is extremely useful in many quests; for example, its run energy-restoring ability can be put to excellent effectiveness in The Fremennik Trials.
