If you have one of these in rook and already reached lvl 8 you may want to keep it, if you are going to Carlin. A common strategy in rook is to buy as many carlin swords as the rookgaardian can carry and sell all their equipment to other rookgaardians and make a hefty profit on the carlin swords in Main, although this may not be recommendable now that one goes to the Island of Destiny at level 8 (Raffael doesn't buy Carlin Swords).
