[[File:Difficulty-slider-t1.jpg|thumb|400px|Difficulty D3's difficulty selection interface.]]Difficulty in Diablo 3 and Reaper of Souls has changed greatly over the course of the game. Upon release  The current system, implemented in [[D3v2]] and [[Reaper of Souls]] in early 2014, allows players to select difficult from Normal up to Torment 6, with monsters increasing in hit points, damage, and exp value with each level. The level of the monsters is entirely scaling though, always changing to match that of the highest level character in the game. In this system, a level 45 character will find level 45 monsters in Act One or Act Five, and all the monsters will increase in level as a character levels up. This is a big change from the system the game mirrored launched with, which emulated the previous Diablo titles. In D1 and D2 and [[D3v]], with difficulty all the monsters were pre-set to specific levels, staggered over 4 difficulty tiers known as [[Normal]], [[Nightmare]], [[Hell]], and [[Inferno, the fourth level new in Diablo 3]]. Each difficulty level tier repeated the same content, with only the levels of the monsters rising in level and ability, and their the various gold, items, and experience values exp rewards increasing proportionallyproportionately. On top of that players Players could set their desired further customize the difficulty by setting the [[Monster Power]] level from 1-10, which was similar to further customize the difficulty and rewardscurrent Normal-Torment customizable system.
