Legio Quartus chathead

Legio Quartus is one of the bosses in the Monastery of Ascension. Accessing him requires an Ascension Keystone Quartus and 95 Slayer.

Like all the Legiones, he attacks with magic and periodically throws energy on the floor, which damages players who step on to it. His unique ability activates when he reaches 75, 50, and 25% intervals, which teleports all the players in the room next to him and summons lightning at the arrival location of the teleport (giving a short time to move away).

Trivia

  • Legio Quartus is roughly Latin for "Fourth Legion". However Legio is a feminine noun, while Quartus is a masculine adjective; the correct form would be Legio Quarta. Legions were the largest units of the Roman army and there were 6 in a whole army, hence there are six legiones in the Monastery.
