Crumble:

Crumble (minor) by Mephisto

This unusual power enables a character to touch a fortification (building, door, wall, sidewalk, etc) and take its properties into him or herself. The character is unable to move doing the transfer, becoming stronger and tougher while also weakening the properties of whatever the character is touching. Plastics, organic life, glass and machinery cannot be crumbled, only solid, earth-based material.

Range: Touch only. The character can not move while using the Crumble power, and counts as all of the characters attacks for that melee round. The character can also not use psionics or magic or engage in hand to hand combat while the power is activated, but gets to perform saving throws as normal.

Duration: As long as the character wishes. Effects have a cap (see below for details), but the character can continue to weaken the fortification that the character is touching.

Effects: The character takes the properties of the fortification, using the following table:

Wood: +1 A.R., +5 S.D.C. per minute (Max: A.R. 10, +60 S.D.C.)

Stone: +1 A.R., +5 S.D.C. per melee round (Max: A.R. 14, +100 S.D.C.)

Concrete: +1 A.R., +5 S.D.C. per minute (Max: A.R. 12, +50 S.D.C.)

Metal: +1 A.R., +5 S.D.C. per melee round (Max: A.R. 13, +80 S.D.C.)

Crumbling: As the character gets stronger, the properties of whatever he's touching get weaker; noticeable cracks, imperfections and wear begin to appear as the fortification breaks down. The Crumbling does 4D6 S.D.C. to the immediate 3 foot (1 m) area surrounding the character per melee round, with a "spider-web" effect of spreading the damage by 1D6 per each additional melee round to the outlying area (1 foot per level of experience)(example: Crumbling Chris is trying to break down a wooden door to get inside. The first melee round he does 4D6 damage to the door, not enough to damage it but enough to weaken it. The next melee round he does still 4D6 damage to the door, but also 1D6 damage to a 3 foot area around the door (as he's fourth level). This damage affects the door jamb, hinges, and arch of the door, but that is as far as the damage spreads.)

Limitation: The extra A.R. vanishes at a rate of one point every hour, and the extra S.D.C. one point every five minutes (12 S.D.C. per hour).
