Just as an Info for everyone who is using the Unofficial Skyrim Patch: If you equip the "Staff of Jyrik Gauldurson" it applys the effect "Jyrik's Blessing". It gives you a bonus of 25 points of magicka and 0.25 more magicka regeneration. The description of the effect in the active effect list is: "Additional Magicka and enhanced Magicka regeneration while holding the Staff of Jyrik Gauldurson.".
Since the wiki only descripe the vanilla game I thougt it would be good to have the Info at least here in the comments. Would it be ok to add this as a trivia or in the bug section, since it is a (unofficail fixed) bug? I never made any changes here, so I am not sure of the rules.
