Overlord: Rising Hell is the official expansion pack to the original Overlord. Along with an extended story, Raising Hell also features new weapons and armor to be forged in the forgery of the Overlord's Tower. To forge the new items, first the player has to locate the mold for each item and bring it back to the tower forge, for it to be imbued with minion life force (like original weapons and armor). The new items have more noticeable effects however. For example, there are weapons that invoke fire damage, and can deal shock attacks (as opposed to simple strength power-ups). There are also helms that can double the amount of life force received after defeating enemies. The new items are not limited to the new areas, and they can be used in the original lands as well as the tower dungeon.
