Guthallath
CREATURE 19A guthallath is an enormous construct created long ago, probably as a war machine, by a long-forgotten empire. 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, the relic is buried up to its neck, covered in moss, and stranded in a 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 to any who stand in its way.
While a guthallath's ancient enemies are likely gone, it's still an engine of pure destruction, designed to rampage for weeks, even months. It's not intelligent enough to enjoy or regret its acts and cannot be reasoned with—it's also unaffected by most magic and unpredictable in how it selects its targets (and the creatures it spares).
A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
120 feet.
The guthallath erodes away the physical integrity of all around it. Creatures and objects in the emanation other than the guthallath have their Hardness and resistances reduced by 10.
At the start of their turn, a creature in the erosion aura's area takes 6d6 bludgeoning damage with a DC 39 basic Fortitude save.
The guthallath is immune to spells of 6th rank or lower and activations of magic items of 13th level or lower.
The Guthallath can choose either Improved Grab or Improved Push 20 feet when it hits with a fist attack.
A guthallath releases two beams of destruction from its eyes. Each beam is a 120-foot line. Everything in either line takes 13d10 damage with a DC 41 basic Fortitude save.
A creature reduced to 0 HP is reduced to a fine powder as the Disintegrate spell. 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.
The creature being landed on can attempt a DC 41 basic Reflex save.
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.
Huge or smaller, foot, DC 45 basic Reflex
The monster Strides up to double its Speed and can move through the spaces of creatures of the listed size, Trampling each creature whose space it enters. The monster can attempt to Trample the same creature only once in a single use of Trample. The monster deals the damage of the listed Strike, but trampled creatures can attempt a basic Reflex save at the listed DC (no damage on a critical success, half damage on a success, double damage on a critical failure).
The monster can instead use Improved Grab as an action and choose one creature it's grabbing or restraining with an appendage that has Improved Grab to automatically extend that condition to the end of the monster's next turn.
