Explorer's ring 4

The Explorer's ring 4 is a reward from the hard Lumbridge and Draynor Tasks. It is an upgrade of Explorer's ring 3.

It has all of the abilities of the lesser rings, including the silver and gold rings' ability to cast the Low Level Alchemy spell 30 times a day (without using any runes). It also has new abilities:
 * It can cast the High Level Alchemy spell 15 times per day (without using any runes).
 * It can cast the Superheat Item spell 27 times per day (without using any runes).

Please notice the following advantages are not counted as part of the ring abilities: (Once the hard task set is done, these effects are gained regardless of whether the ring is worn)
 * A food hamper can be collected from the Lumbridge Cook daily.
 * A 50% chance of not using runes when casting the Bones to Bananas spell, up to a maximum of 10 times per day.

Trivia

 * On the day of release a bug prevented the alchemy options to be cast twice at a fast pace. If a player were to use either of the ring's alchemy, they would have to wait until the casting animation completely over before casting it again, otherwise they would be able to reactivate the spell but unable to actually choose an item to cast it on. This has been fixed.
 * The Explorer's ring 4 had the ability to alchemise itself. The Explorer's ring 2 and 3 became able to alch themselves too since the release of elite tasks, but all the rings are fixed of the bug, on 21 September 2010.
 * Contrary to popular belief, this ring does not give 4 charges of running energy daily.
 * This ring did not give the ability to craft extra elemental runes (such as explorer ring 3 and 2 did) early in its release, but effective the 17 January 2011 update, the ring has this ability.
 * Using all the spell properties of the explorer's ring 4 will yield a total of 3,336 Magic XP daily as follows:
 * 30 low alchemy at 31 XP = 930 experience
 * 27 superheat at 53 XP = 1,431 experience
 * 15 high alchemy at 65 XP = 975 experience
 * These values are Magic experience only and are in addition to any Smithing experience superheat grants.
 * Fully utilising the ring as above will yield 23,352 experience weekly, or 1,217,640 yearly.
 * Effective the 2 November 2010 update, the low alchemy, high alchemy and superheat interfaces have been reworked to make them much more user friendly.
 * An early November 2010 update (possibly the BOAESU) has fixed the glitch with the Explorer's Ring 4 not showing "Your Explorer's Ring has been recharged" text for the first login after midnight Jagex time.
 * A hidden update capitalised the explorer's ring name in the recharge message.
 * On 22 February 2011, the Explorer's Ring superheat item ability was noticeably slowed to match the speed of low alchemy. The casting speed was restored a day later.
