Rappelz/Items

Rupees
The Rupee is the in game currency used worldwide; there are no varying amounts like in World of Warcraft (Copper, Silver, etc.) that help keep numbers to a minimum. High level players thus earn vast amounts of Rupees, and items often cost several million.

Lak
Lak is a special feature of Rappelz; it acts a special drop from monsters that accumulate within a player's necklace. Lak, being rare, can be traded at a Lak Trader NPC (found in towns) for either Boost Chips or Rupees. To most effectively use Lak, players need to determine the right amount of either so that they do not end up with too many or too few Boost Chips. If that happens, then they must either sell them (only if a low level player levels and is able to use a higher rank boost chip) or buy more. The problem though is that the conversion rate used in Lak trading is higher than the selling and buying rates at merchants; thus Rupees are lost in the process.
