The Domination league and Nemesis league ran from October 23, 2013 to February 23, 2014.
Rare monsters have one guaranteed mod from the Nemesis Pool, which makes the fight substantially harder.
The Nemesis league was a four month challenge league aimed at players who are looking for more challenging gameplay. In this league, every rare monster had one powerful Nemesis modifier, making them even more deadly.
It started, along with the Domination league, on October 23, 2013 and lasted until February 23, 2014. At the end of the league surviving characters and stashes were moved to the Hardcore league. As with regular Hardcore, characters that die during the four months were moved to the Standard league immediately.
All areas had the following modifier: Rare Monsters each have a Nemesis Mod
Nemesis had seven exclusive base item types (all shared with Domination) and seven exclusive uniques (six of which were shared with Domination). The new base ring type Prismatic Ring did not drop from slain enemies, and instead was only obtainable by using a new vendor recipe. The Item Quantity Support gem could not be obtained, and IIQ mods could not spawn on magic and rare items.
