ability for towers

cost 6 turns
produced at advancement center

machicolation
hp -0.6
affects enemies around the tower
damage multiplied by tower attack

There were some similar ideas such as burning oil, murder holes etc. these ideas should b merged

maybe this affects towers and oil affects forts and castles

But it is used to throw oil, stones etc.

well yea...mmh machicolation its more generic...so i think it fits better and its not restricted to a single way of using the element. so the tech could be machicolation, and the spell could be throw oil
