The Killithid's portals will continue to fire after the Killithid has been frozen. This can be used to find the original quickly and without wasting bullets. While firing, Killithid illusions can be pushed around but the original cannot. The content on this page is NOT official or canon to Enter the Gungeon, or any other Dodge Roll property, and has not been created or reviewed by Dodge Roll. If the original Killithid is being jammed by a Jammomancer and creates illusions, those illusions will be jammed, even if the Jammomancer is killed. If the original Killithid is under a status effect such as poison when it creates illusions, only the original will have the status effect, allowing it to be easily spotted. The symbols that appear above Killithid when it attacks (the blue X, the pink square, the red circle and the green triangle) are a reference to the PlayStation DualShock controller.
