What is Nightmare in AION 2?
Nightmare is a high-end boss challenge in AION 2, built around a series of layers that get progressively harder. Each layer has its own bosses and challenge level, rewarding players who can push deeper. It’s a key gear and progression milestone for end-game characters.
The Nightmare layers
Nightmare is split into Layer I, Layer II and Layer III, each tougher than the last. The deeper you go, the higher the challenge level — and the better the rewards. Our database breaks down every layer so you know exactly what’s waiting before you queue.
All Nightmare bosses
From the Gatekeeper Pinopi onward, every Nightmare boss is catalogued by layer. Check each encounter ahead of time, plan your approach, and walk in knowing what you’re up against instead of learning the hard way.
Challenge level & rewards
Each Nightmare boss has a challenge level that tells you how much character power you’ll need to bring. Use it to gauge whether your build is ready, and to set a target before you head back to the build planner to push your stats higher.
