Diablo III PTR 2.6.5 - Season 17 Legacy of Nightmares
The Diablo III PTR 2.6.5 will go live on Friday, April 5; and it will last for a week to test Season 17 -- which features an insane buff.
The Season of Legacy of Nightmares ruleset says:
Player’s damage dealt is increased by 750% and damage taken is reduced by 4% for every Ancient Item they have equipped while having no Set Bonuses Active.
Other highlights of Patch 2.6.5 is that Torment 14, 15, and 16 have been added into the game. Read the full patch notes.
