Kirk, Knight of Thorns is a Black Phantom NPC who will invade your game at three possible locations. These are Depths, Demon Ruins and Lost Izalith. As with all invasions, you must be in human form and the area Demon must still be alive.
- Depths: Gaping Dragon must be alive. Head down below the Giant Rat to the lowest parts of the sewer.
- Demon Ruins: Demon Firesage must be alive. Coming from Quelaag's Domain, just passed the first Capra Demon, on the thin ledge down to the group of Capra Demons.
- Lost Izalith: Bed of Chaos must be alive. Just outside the final fog gate.
