Bethesda will release yet another cool plug-in for Xbox 360 and PC Elder Scrolls IV: Oblivion players. The new plug-in is called Spell Tomes - DLC4 and adds “Spell Tomes” to the world’s random treasure. These books grant players powerful magic spells, just by reading them. Now Mages will also gain instant benefits by treasure hunting. Spell Tomes includes hundreds of new spell-giving books, low level and high level spells, new powerful spells with multiple effects and extremely powerful new spells that are balanced with slightly detrimental effects to lower the cost in Magicka. Look for the pack on Thursday, August 31st. Find out more at obliviondownloads.com . And look for the Xbox 360 version on Xbox Live Marketplace.
