Oathbound: The Hollow Delve

Survive an 18-minute dungeon expedition, build an absurdly powerful hybrid hero from automatic weapons, relics and evolutions, then defeat the final guardian before the dungeon collapses.

The kingdom of Veyr sealed a disaster beneath its capital with an oath that no soul would be forgotten. Its keeper took the promise literally, and the Hollow Delve now repeats every lost life forever. You belong to the Lantern Compact: fall below and your lantern brings you home.

• Movement is the skill. Your weapons fire on their own; you dodge warned attacks, pick your fights and grab experience.
• Build a hybrid hero. Six classes. At level 8, choose a second discipline for one of 15 hybrid rules: Runeblade, Spellhunter, Wildpact and more.
• Evolve your weapons. Twelve weapons and twelve relics. A rank-5 weapon plus its recipe relic transforms into a legendary form at an evolution altar.
• Bargain with the dungeon. Accept optional Edicts from the Hollow Voice: timed challenges with clear rewards and clear risks.
• Three dungeons, three bosses. The Candle Ossuary, the Rootbound Court and the Shattered Orrery each end with a boss and a two-minute deadline.
• Lasting progress. Spend Remembrance on training, unlock classes and dungeons, recover story pages and climb five Ascension tiers.
