Ajjat is a former Kinshra knight, who sells the Attack cape to those who have reached 99 Attack. He can be found on the lowest floor of the Warriors' Guild. To enter the guild, one must have a combined Attack and Strength level of 130 or a 99 in of one of those skills.
He appears to be wearing tattered and spiked black trimmed armour, and is wielding what seems to be a broken black 2h sword.
The tokens given from his activity in the Warriors' Guild are used to gain entrance to a room full of cyclopes at the top or in the basement of the guild (100 tokens = 10 minutes inside the room). Cyclopes have a chance dropping a defender, which can be shown to the person outside the door of the cyclops room, they will then allow you to gain the next defender up in the sequence (bronze to rune, with dragon in the basement).
