Rend Earth

Rend Earth (minor) by Stone Gargoyle

This is based on the sub-ability of CEF: Earth, HU2 main book page 258.
The super being can split the earth like a mini-earthquake, creating a 15 foot wide, 20 foot deep, and 40 foot long crevice. These are the maximum measurements and can be adjusted to the super being's desire by increments of one foot. The opening can be made up to 300 feet away and can be performed once every melee round. Thus its creator can add to its length every 15 seconds or create several different chasms.
This ability also enables the superpowered character to create openings in the walls of concrete, rick, plaster or stone (not wood) buildings. Even after the super being closes the wall, there will still be a noticeable crack, and at least minor structural damage, varying with the size of the earlier opening.

Range: 300 feet + 30 feet per level of experience.

Duration: The openings in the earth will remain until closed by the super being.

Damage: Falling into the chasm does 3d6 damage. Climbing down takes about two melee rounds; climbing up its sheer wall, four melee rounds. Rappelling is the bast way up and down.
Vehicles falling into the chasm will suffer 1d4X10 damage if they weren't moving or were traveling under 10 mph. Otherwise, add 4d6 damage for every additional 10mph.
Crushing Damage: The creator of the opening can also close it at any time (counts as two melee actions) and only one can be closed per melee round, and not in the same round that it was opened. It will close in one melee round (15 seconds) and will crush everything that has fallen into it like a giant vise! Damage is 2d4X10+40 (double damage to vehicles and large, crunchable objects). Dense, solid objects will suffer one quarter the damage, but will be completely buried. Note: Those not killed by this are buried and will suffocate within 3-4 minutes. Super beings who can dig tunnels should be able to dig themselves out. Those with Superhuman or Supernatural PS may also be able to slowly dig their way out, provided they don't run out of air. Those who have vast amounts of SDC will survive the crushing but will suffocate unless they don't need to breathe air or can hold their breath for a long period. Those with energy expulsion powers will be able to blast themselves an underground cavity to avoid being crushed and may also be able to blast an opening to the surface. People trapped inside vehicles that survive the crushing damage may also have a pocket of air. In chasms opened in urban areas, sewer and drain pipes may be ripped open (or be opened) to provide an escape or temporary safe haven.

Attacks Per Melee: The opening or closing of a chasm can only be performed once per melee round and uses up two melee attacks/actions.
