Could argue either way. "Field-" has simpler ring to it, but "Juggernaut-" more accurate in some ways.
Let's use Juggernaut. I'll attempt a clearer version and a simpler version:
Juggernaut of Destruction (Recharge 5-6). The gurgohemoth moves up to 80 feet, trying to crush underfoot (see below) any creature in its path that is smaller than itself. This attack covers the 20-foot-square space occupied by the gurgohemoth's starting position plus the 20-foot wide zone the gurgohemoth's space enters as it moves along this path of destruction. The movement stomps over Large or smaller creatures on the ground without slowing, but prone Huge creature counts as difficult terrain. If the juggernaut path of destruction contacts a non-prone Huge creature, the creature must make a DC 24 Strength saving throw or be knocked prone and crushed underfoot. On a success the gurgohemoth cannot enter the Huge creature's space and they take no damage, ending its path of destruction. The path of destruction cannot move over or damage a Gargantuan creature even if it is prone, although the gurgohemoth may be able to sweep the creature out of its path (see sweep and crush).
The gurgohemoth can also sweep up to three areas with its trunk and tusks, each swept area costs 10 feet of movement. The gurgohemoth can sweep across a 20 ft. by 20 ft. square (in any direction) or along the length of a 15 ft. by 30 ft. rectangle or a 10 ft. by 50 ft. line; the sweep always has a direction that determines the order creatures in its area are affected. Swept areas can overlap with each other but this does not increase their effectiveness. Every part of a swept area must be within 20 feet of the gurgohemoth's path of destruction. The gurgohemoth can sweep an area and then stomp over it, affecting creatures in that area with sweep and crush (see below) instead of crush underfoot or sweep. A gurgohemoth cannot sweep through a Gargantuan creature or object, such obstacles are affected by the Sweep (or Sweep and Crush) but block the swept area from extending past them.
Creatures in the path of destruction or swept are affected as follows:
- Path of Destruction: Each creature in the path of destruction must make a DC 24 Dexterity saving throw or take 42 (6d10 + 9) bludgeoning damage and be knocked prone. Large or smaller creature take no damage if they succeed, Huge creatures take half as much damage if they succeed.
- Sweep: Each creature in the swept area much make a DC 24 Dexterity saving throw or take 30 (6d6 + 9) bludgeoning (falling) damage, or half as much damage on a successful one. With a failed save the target also suffers the following:
If the target is Huge size or smaller, they are tossed a distance of 40 ft. (8d6 + 12) in the direction of the sweep, or 20 ft. (4d6 + 6) for a Huge creature. If the gurgohemoth hurls its victim over a cliff or into a pit that also causes falling damage, the target takes whichever falling damage rolls higher (do not add the sweep's 6d6 + 9 falling damage to other falling damage).
If the target is Gargantuan size, the sweep hits their legs and slams the creature into the ground, causing them to fall prone.
- Sweep and Crush: Identical to Sweep except each creature in the area takes 42 (8d6 + 14) bludgeoning (falling) damage, or half as much on a successful save. the target is Gargantuan size, the sweep hits their legs and slams the creature into the ground, causing them to fall prone. There is a 50% chance the Gargantuan creature will fall off to one side of the path of destruction, allowing the gurgohemoth to continue along the path at the cost of 10 feet of movement.
Here's the simpler version, with the complexity of sweeping removed:
Path of Destruction (Recharge 5-6) #2. The gurgohemoth moves up to 80 feet, trying to crush underfoot any creature in its path that is smaller than itself. This attack covers the 20-foot-square space occupied by the gurgohemoth's starting position plus the 20-foot wide zone the gurgohemoth's space enters as it moves along this path of destruction. The gurgohemoth stomps over Large or smaller creatures on the ground without slowing, but prone Huge creature counts as difficult terrain. If the juggernaut path of destruction contacts a non-prone Huge creature, the creature must make a DC 24 Strength saving throw or be knocked prone and stomped. On a success the gurgohemoth cannot enter the Huge creature's space and they take no damage, ending its path of destruction. The path of destruction cannot move over or damage a Gargantuan creature even if it is prone.
Each creature in the path of destruction must make a DC 24 Dexterity saving throw or take 42 (6d10 + 9) bludgeoning damage and be knocked prone. Large or smaller creature take no damage if they succeed, Huge creatures take half as much damage if they succeed.
Hmm, that makes me realize there's a better way to work the Juggernaut version:
Juggernaut of Destruction (Recharge 5-6) #2. The gurgohemoth moves up to 80 feet, trying to crush underfoot any creature in its path that is smaller than itself. This attack covers the 20-foot-square space occupied by the gurgohemoth's starting position plus the 20-foot wide zone the gurgohemoth's space enters as it moves along this path of destruction. The gurgohemoth stomps over Large or smaller creatures on the ground without slowing, but prone Huge creature counts as difficult terrain. If the juggernaut path of destruction contacts a non-prone Huge creature, the creature must make a DC 24 Strength saving throw or be knocked prone and stomped. On a success the gurgohemoth cannot enter the Huge creature's space and they take no damage, ending its path of destruction. The path of destruction cannot move over or damage a Gargantuan creature even if it is prone, although the gurgohemoth may be able to sweep the creature out of its path (see below).
Each creature in the path of destruction must make a DC 24 Dexterity saving throw or take 42 (6d10 + 9) bludgeoning damage and be knocked prone. Large or smaller creature take no damage if they succeed, Huge creatures take half as much damage if they succeed.
The gurgohemoth can also sweep up to three areas with its trunk and tusks, each swept area costs 10 feet of movement. The gurgohemoth can sweep across a 20 ft. by 20 ft. square (in any direction) or along the length of a 15 ft. by 30 ft. rectangle or a 10 ft. by 50 ft. line; the sweep always has a direction that determines the order creatures in its area are affected. Swept areas can overlap with each other but this does not increase their effectiveness. Every part of a swept area must be within 20 feet of the gurgohemoth's path of destruction. A gurgohemoth can sweep an area and then overlap it with its path of destruction, but it cannot sweep into its space or the path behind it. A gurgohemoth cannot sweep through a Gargantuan creature or object, such obstacles are affected by the Sweep but block the swept area from extending past them.
Each creature in the swept area much make a DC 24 Dexterity saving throw. If they fail, they take 30 (6d6 + 9) bludgeoning (falling) damage, or half as much damage on a successful one. Should the swept area overlap with the gurgohemoth's path of destruction, the creature takes the path of destruction's 42 (6d10 + 9) bludgeoning damage instead of the sweep's normal damage even if the creature is Gargantuan, or half as much damage on a successful save. With a failed save the target also suffers the following:
If the target is Huge size or smaller, they are tossed a distance of 40 ft. (8d6 + 12) in the direction of the sweep, or 20 ft. (4d6 + 6) for a Huge creature. If the gurgohemoth tosses its victim over a cliff or into a pit that also causes falling damage, the target takes whichever falling damage rolls higher (do not add the sweep's 6d6 + 9 or 6d10 + 9 falling damage to other falling damage).
If the target is Gargantuan size, the sweep hits their legs and slams the creature into the ground, causing them to fall prone. If the sweep overlaps with the path of destruction, there is a 50% chance the target will fall off to one side of the path, allowing the gurgohemoth to continue along the path at the cost of 10 feet of movement.
Which do you like the best?
Juggetnaut #2 is my favorite but
Path #2 is a good follow-up.
