Meg: A huge lamp that smells of the sea.
A huge XP lamp is a very rare prize rewarded from the Squeal of Fortune or Meg, which grants the player a definite amount of experience scaled to the selected skill level. It grants twice the experience of a large one, four times the experience of a medium, or eight times the experience of a small one. As with most lamps, this item may not be stored in a bank. The experience gained stays constant from level 99 to 120.
If the player receives one of these lamps, it is highly recommended to utilise it on a skill that is either expensive, such as Prayer, Herblore, or Construction, or time-consuming, such as Slayer, Farming, or Agility. It should be noted that if one decides to use it on an expensive skill, they must also take into consideration the 500k sacrificed to claim the reward. For example, at level 70 and below, the cost per exp is close to 25, much higher than the cost of efficiently training herblore or prayer.
An update on 12 October 2012 replaced skill-specific huge lamps in Construction, Crafting, Farming, Herblore, Smithing and Summoning by crates containing training items for the skills. However, it is still possible to receive a huge xp lamp for these skills instead.
The following is an XP table detailing the number of experience received from a huge lamp for any given skill level:
|Skill level||Experience||Skill level||Experience||Skill level||Experience|
Below is a polynomial formula which loosely approximates the experience gained in a skill at level L.
One can also use the following less accurate exponential formula to approximate experience gained at level L:
- Unlike other very rare rewards, winning a huge XP lamp on the Squeal of Fortune does not produce an event on one's adventure log.
