Am 5. März soll die kostenlose Erweiterung "Sacrifice of the Vaal" für Path of Exile veröffentlicht werden. Das Update auf Version 1.1 dreht sich um Atziri (Queen of the Vaal) und umfasst verderbte Gebiete sowie Gegenstände, neue Skill-Gems der Vaal-Zivilisation, weitere Bossgegner, zwei zusätzliche Ligen (Ambush und Invasion) und zwei PvP-Modi.
Like the Anarchy and Domination challenge leagues before it, the Ambush league is about risk and reward. Various new types of chests called Strongboxes can be found throughout Wraeclast. These chests are guarded by monsters that ambush the player when they are opened. The ambushing monsters must be slain before the contents of the Strongbox can be claimed. Sometimes you'll encounter magic, rare or unique Strongboxes which have mods like items do. Prefixes affect the difficulty of the ambush by adding more monsters, springing traps or affecting your character. Suffixes improve your rewards from the Strongbox. You can use currency items to reroll these mods.
Like the Onslaught and Nemesis leagues before it, Sacrifice of the Vaal's hardcore Invasion league is designed to kill players. In the Invasion league, areas of Wraeclast have substantially more monster variety, so players will run into unexpected and dangerous invading monsters from other levels or acts. A unique boss monster from an invading monster type is also lurking in each level, with powerful combinations of skills to catch the player off-guard. As you progress through Path of Exile's difficulty levels, the monster variety continues to expand and the invading bosses gain additional abilities.
