A Magic Item has a Magic Prefix, or a Magic Suffix, or one of both. A Magic item can never have two Prefixes or two Suffixes.

When Magic Items are created the chances are:

Both Prefix and Suffix: 25%
Only a Prefix: 25%
Only a Suffix: 50%

Selecting Prefixes/Suffixes in drops from Monsters
When picking Prefixes and Suffixes, it will, among those that can occur on the specific base item being created, randomly choose from all those that has a qlvl<=ilvl+2.

qlvl= The Level of the Magic Prefix or Magic Suffix. Look on those pages for the level listed next to each item.

The ilvl is defined as the Monster Level for monsters. Fan sites typically have listings of monster levels.

Magic Level
Circlets, Staves, Wands and Orbs have a special magic ability, or Magic Level, which allows players to receive higher level magical Prefixes and Suffixes on items from Monster Drops and when Gambling (Circlets Only). This bonus only applies to the bonuses that appear on the items themselves. This does not help generate better Magic Prefixes and Suffixes on other items if you are wearing them. So when you receive a Circlet via Gambling or a Monster drop the Magic Level helps increase the chances that a better Magic Prefix or Suffix will appear on it.

Circlets have an increased Magic Level which can add to the Monster Level which can allow you to receive higher Magic Prefixes and Suffixes.

Selecting Prefixes/Suffixes in Gambling
When selecting which Magic Prefixes/Suffixes are available to be Gambled, the level of the Magical Prefix/Suffix is checked against the randomly chosen value in the range of +6 Levels/-3 levels of your character's level. So a Magic item with a Prefix level of 90 would be available at Character Level 84. The chance of getting that item also becomes better at higher Character Levels.
