The Colosseum is an Act 2 Event, but only appears in the top half of the act. It forces a fight with two Slavers, then gives the player the option to fight more enemies for a large reward.


Begins a battle with Blue Slaver and Red Slaver.

Once the battle is over, the following 2 options are given:


Brings up the map screen.

[VICTORY] A powerful fight with many rewards.

Begins a fight with a Taskmaster and a Gremlin Nob. The reward is 100 gold, 1 rare and 1 uncommon relic, and a standard card selection.

Tips Edit

  • While the fight with the slavers is not optional, the second fight is completely optional.
  • A Smoke Bomb may be used to avoid the confrontation with the slavers. This then brings up the choice of escaping or fighting the Taskmaster and Gremlin Nob.
  • (Doesn't apply since v1.0) As the Gremlin Nob is in front of the Taskmaster, it cannot apply Icon Vulnerable Vulnerable, but it is still powerful and gains Icon Strength Strength from Skills played; it should be dispatched quickly. The Taskmaster, on the other hand, can fill your discard pile with Wounds
    , but does less damage overall.
