[Cathan's Traps]

This is a very nice level of health stealing, and especially on a ring.  This sort of modifier is more commonly found on a weapon, but with it on the ring your weapon is free to go for all the damage possible.  The Amulet isn't quite as useful, though you do get an unusual "attacker takes lightning damage" modifier on it.  This property has not been seen on any other items in the beta.

• Set items in Diablo II appear to all use normal item graphics, some with a palette shift.  Unknown if there will be any custom graphics for them in the final, or if this is it.  Jewelry graphics are picked randomly from the types that can be found in the beta.
• All Set Items in Diablo II have a Clvl requirement that is (apparently) the same for every item in the set.  These numbers have been modified during the beta, and may change again before the final.  The requirement to equip items in this set is Character Level 11.
