** At lower levels many items have +experience per kill. These are effective in the early going, but fade to insignificance at higher levels.

** Some [[Legendary]] items have +% experience gain properties, including the [[Hellfire Ring]], [[Leoric's Signet]] ring, and [[Cain's Honor]] item set.

*** Experience gain equipment on [[Follower]]s grants a benefit to the character, but only at 20% of the value. (Thus the 35% from a Hellfire Ring is worth 7% when equipped on a Follower.) Note that Followers can only equip weapons, rings, and amulets (shields as well on the [[Templar]]).

* When multiple players are in the same game their experience gain is multiplied by 10% for each extra player except the first one. (The bonus goes up to 30% with a full party of 4).

For players serious about level up speed, it's a good idea to keep a log. Record the starting time of each game, note your equipment, [[build]], and the MP level, then record the total time of the game and your ending experience. After a few trials the data should make clear which strategies are yielding the best experience over time.
