We are updating regular (not personal) artifacts in order to make more players interested in them. The regular artifacts which will be changed so they cost less then they used to will be removed from the possessions of their owners and the old cost of such artifacts in platinum will be added to their owners bank accounts. It is now possible to use Platinum Bars to add essences to regular artifacts as well as personal ones. However the regular artifacts that has not been updated yet will receive the increase of Wondrous bonuses as if they were artifacts with added grade of 0.4.
