Loop Dungeon - Incremental heroes

Loop Dungeon - Incremental lets you unlock heroes with different roles and abilities. Official screenshots show an Archer, a Mage and a Priest, and the full release added the Rogue, a damage hero with a Blink Attack. The Priest received a new skill, Activate, that interacts with other heroes' skills.

Rogue

The launch post pitches the Rogue at players who like high burst damage. Blink Attack lets her close in on enemies quickly. Numbers for her damage have not been published.

Priest: Activate

The developer says Activate can combine with other heroes' skills for unexpected effects and leaves the combinations for players to find. No list of interactions is published.

More heroes

The developer mentions "more heroes" in the full game without naming all of them, so this list covers only heroes that have been shown or named.
