Modifers in Diablo II are more numerous, potent, and enjoyable than they were in Diablo, and that is saying a lot.  Hundreds of new modifiers exist, and there is a much larger variety of them to be found as well.   There are even special modifers that can only be found from the hardest monsters on the highest difficulty level, so the cheesy normal/hell item runs of Diablo are not going to be anywhere near the best source of items this time around.

Suffixes work just as the did in Diablo.  They can only occur after the name of the item type, and each suffix has certain prefixes it can and can not occur with.  Similar levels work together, as they did in Diablo.  One added complication is that Rares, Uniques, and Item Sets list all of their modifiers by effect, and they can mix and match prefixes, suffixes, and other modifiers freely, so it's difficult to tell what exactly is giving the item a given property. Crushing Blow, of Chance, Open Wounds, of the Sun, of Fortune, of Lightning, and info about higher Clvl requirements on Jewelry.

Suffixes on Magical Items

Magical items have one or none, Uniques and Rares can have more than one.  Suffixes are distributed to their appropriate item type, just as they were in Diablo, and occur in sequential families.  This listing is alphabetical, rather than grouped by effect.  This table is accurate for the beta, but expect hundreds more suffixes in the final game, and also expect the ranges and item types occuring on to be extensively modified from their current state.

Open Wounds results in the monster bleeding uncontrollably and taking extra damage over time, similar to poison. It can not, however, be resisted like poison can.

A successful Deadly Strike results in double damage being dealt. This can be combined with Critical Strike for 4x the normal damage.

A successful Crushing Blow, on the other hand, will reduce a monster's health by 50%.
