Ring Of The Sea Strider

This ring is made of a single piece of deep blue crystal. The ring grants its wearer a swim speed of 30 feet, as well as +8 racial bonus on swim checks for having a swim speed. Furthermore, once per day as a swift action, as long as the wearer is in contact with liquid, he can use dimension door as the spell, but its starting and ending points must be connected by a contagious mass of liquid.
