Wearing the medallion will also give a boost in Attack, Strength, Defence, Ranged, and Magic for as long as it's worn inside the tower. The size of the boost is dependent on your levels, with level 99 giving a +8 boost roughly once a minute, maxing at 107. This is often used in conjunction with Saradomin brews to reduce the necessity of stat restoring potions.
This medallion provides three teleports a day to the Dominion Tower and recharges daily.
Currently, removing the super dominion medallion will also remove any stat boosts, even those granted by other items or sources, and even outside the Dominion Tower.
