Sila lamp

A Sila lamp was a special type of XP lamp that required you to join a lamp pot, lamp handle, and spout of the same type. You could not mix and match other genie lamps. When combining the parts, players would be notified that the process is irreversible and the lamp would become untradeable. If the lamp parts were combined, the lamp became unbankable, and the lamp must have be used or kept in inventory. Players would gain experience in Constitution, Magic, Prayer, Runecrafting and Summoning when they rubbed the Sila lamp. You could disable the reward exp in the Magic skill by talking to Jasper near the Duel Arena.

This lamp could be combined with the four other Genie lamps as well as a bottled genie, to form the Lamp of the Djinn. Experience from this lamp was roughly 25% more than the xp of a medium XP lamp in your chosen skill, and roughly 50% of a small XP lamp's xp in the other 4 skills. At level 99, players were awarded 21,505xp in the chosen skill, and 4,301xp for each of the other 4 skills. Parts for all 5 base lamp types were findable while skilling or in combat. While the parts for these lamps were not sellable or tradeable in the normal sense, they were made exchangeable in a face-to-face trade with other players for an equivalent number of lamp parts. To trade them there must have be an equal number of lamp parts on both sides of the trade, and no money or other items in the trade at all.
