Blizzard has issued a hotfix for Diablo III which increases the chance of high-end loot drops by monsters in all Inferno acts, and acts 3 and 4 in Hell mode. The chance of looting level 63 items have also increases significantly, and bosses are now guaranteed one Rare item at the least for players with four stacks of Nephalem Valor. If a player has five stacks of Nephalem Valor, bosses will drop at least two Rare items. The list of hotfixes can be found through here, but note that if you have yet to finish the game on Normal difficulty, the list may contain some spoilers.
