“I remember that day clearly. My raiding party was crossing the straits to the Isle of the Mist looking for some easy plunder. It was a good day, a day of song and good hard work at the oars. Then It rose from the waters. Like a man, but not, and made of stone and strange metals. With one fist it crushed our and sent my crew to their grave.”

The Titans are mechanical constructs created by a long dead, but highly advanced race. A miracle of science and magic, the titans are clock work automatons infused with Old Magics making them virtually indestructible.
Six magically wards (crown of the head, shoulders, mid-back, small of the back and center of the chest) empower the Titans giving them their near indestructibility. Only by destroying the wards(AC 4  each 3 HD) can a Titan’s power be broken and the automaton destroyed. This brings the titan’s AC[AAC] to the second set of numbers and removed the creature’s resistances.
When a titan hits the ground with either of its attacks it has a 75% chance to cause a small localized earthquake that can knock anyone within a 120 feet of its fist to the ground and cause 1d4 damage.
