The Tower Warden

From the OblivioWiki – your guide to everything Oblivion

The Tower Warden is a Lesser Power afforded to those born with The Tower Birthsign. Once a day, a player may choose to invoke this power, which allows them to reflect 5 points of damage (regardless of type or source) for 120 seconds. (2 minutes) Attacks dealing more than 5 points of damage have the 5 points subtracted from the damage the player receives, and is reflected. The player takes the remaining damage normally.

Players born under The Tower also have access to the Greater Power known as the Tower Key.
