Challenge XP Lamp

A Challenge XP Lamp is a reward that can be given for completing a daily challenge relating to combat. Rubbing the lamp will give the choice to earn experience in one of the following:
 * Constitution
 * Magic
 * Ranged
 * Melee:
 * Attack
 * Defence
 * Strength

Note that the individual melee skills will not be shown upon first rubbing the lamp, but if you choose melee from the first few options you will then be prompted to select from one of the three melee skills.

The amount of experience gained is yet to be determined. Please help out by contributing data to our research on the talk page.

The amount of experience gained, when used on a lvl 75 skill, is roughly 15k.
