Vic the trader

Vic the trader is the owner of Vic's Store and was located south-west of the Burthorpe lodestone next to the bank. Prior to 5 October 2014 he would convert bonus experience from any skill into credits. You could use the credits at his store to purchase prismatic lamps or stars, skill outfit pieces, and rewards which were previously on Treasure Hunter. He is set to return in April 2015.

The cost of credits varied from skill to skill and increased with higher skill levels. In other words, players got fewer credits in higher level skills for the same experience. The cost of the first 200 credits in each skill was reduced 50%.

It costs 2520 (or 90*28) credits in order to have a filled inventory of Huge Prismatic Stars, which yields 2,312,189 bonus experience in a skill already at level 99. Keep in mind that the amount of lamps you can buy from Vic is limited to a maximum of 10 large prismatic lamps and 50 small prismatic lamps.

Trivia

 * The name Vic the trader is identical to an NPC found within the video game . It is possible that Jagex drew inspiration from the Fallout 2 character when creating Vic's in-game name. It is also possible that both names are inspired by the well-known restaurant chain Trader Vic's.
 * While free-to-play players can still access Vic's Store interface, when attempting to 'Trade XP' via the right-click option, free-to-play players are prompted with a message from Vic saying 'Sorry, I can't trade here.'
