Trortur

Trortur is a unique encounter that can be found in the Inner Hall after attempting to enter the lower levels.

He will ask the player if he wants to see something interesting. Accepting this offer will cause the player to be captured and tortured, eventually leading to a game over. If you refuse his offer twice, Trortur will initiate a battle with the player.

Strategy
Trortur is a particularly easy enemy, as he has a low HP pool and low damage.

The player can either choose to reason with him, revealing an NPC hiding in one of the cells. This will get Trortur to gift you with a Light Blue Vial, and a 2F Key, which will lead you down to the prisons.

Alternatively, you can simply cut off his head, which will result in the immediate death of Trortur.

Lore
Trortur wasn't always the evil person you encounter in the game now, little know that he was a famed knight in the city of Rondon back in the day, but during one of their holy crusades, he got captured and sent to the dungeons. Everyone presumed that he was dead, until 5 years later when the knights captured the Eastern Capital Jettaiah and they found what was left of Trortur- a shadow of his former self, a hunch-backed, disfigured creature who learned about every method of torture that he now puts to use himself.
