Erosion Aura (aura, primal) 120 feet. The guthallath erodes away the physical integrity of all around it.

At the start of its turn, a creature in the erosion aura's area takes 6d6 bludgeoning damage (basic Fortitude DC 39).

Annihilation Beams A guthallath releases two beams of destruction from its eyes. Each beam is a 120-foot line. Everything in either line takes the effect of a hit from a 10th-level disintegrate spell (DC 41 Fortitude). There is no additional effect on creatures in any area where the beams overlap. The guthallath can't use this ability again for 1d4 rounds.
Deadly Throw Requirements The guthallath has a creature grabbed.; Effect The guthallath throws the creature into the air, 100 feet high and 50 feet away. If the flung creature lands on another creature, the creature it lands on takes the same amount of bludgeoning damage. The creature being landed on can attempt a DC 41 basic Reflex save.
Powerful Blows If a guthallath hits with an attack and rolls a natural 19 on the d20 roll, the attack is a critical hit. This has no effect if the 19 would be a failure.
Trample Huge or smaller, foot, DC 45
A guthallath is an enormous construct created long ago by some unknown empire, probably as a war machine. Nearly 100 feet tall, this massive stone statue typically resembles a stalwart warrior wearing only a loincloth and skullcap. Few have seen the entire body of a guthallath, though; most of the time such a relic is buried up to its neck, covered in moss and stranded in some forgotten place. Yet, every so often, one of these harbingers of destruction reactivates in response to some unknown stimulus or rallying call, and when this happens, woe be unto any who stand in its way.
While the guthallath's ancient enemies are gone, it is an engine of pure destruction, designed to rampage for weeks or even months. While not intelligent enough to enjoy or regret its acts, the guthallath cannot be reasoned with—it is unaffected by most magic, and is unpredictable in how it selects its targets (and creatures it spares).
Entire civilizations have been swept off the face of the world due to the devastating rampage of a guthallath. But there is a light at the end of the tunnel, for after some time the guthallath ends its massacre in a swift yet seemingly random way. The colossus then finds a remote location deep in the wilderness, where it buries itself, entering a deep slumber for years— if not centuries—before awakening and beginning the destructive cycle once more.
