I have been studying that marvellous piece of engineering, the catapult. I am well versed in the use of the device, and will be offering my services for a generous price of 1000 gold (as a single fee for my mercenary services including fighting). I will expect the hiring army to have bought sufficient materials for my work, as well as a suitable uniform. I also have proficiency with the crossbow, that other deadly contraption, so if there are any going, I would be grateful if I could be allowed one for self-defence. Over to you.
