So some geomancer ideas i wanted to put out there for group suggestions. 

Rock walk: {Requires urban camouflage} When in use, Brick actually shares space with the material he has absorbed for camouflage, granting him the [b][i]merged[/i][/b] status, while [b][i]merged[/i][/b] he cannot be the target of direct attack or Aoe Unless it specifically causes damage to walls (example being demolition charges) in which his defense is treated as 1 for purposes of damage resolution.
***
Gopher Hole: Brick opens a small hole to trap a single limb (attack versus defense) if he succeeds, the enemy is unharmed but [b][i]trapped[/i][/b], unable to ESCAPE but still able to attack.

Snakebite: {requires Gopher Hole} Brick opens a small hole to trap a single limb (attack versus defense) if he succeeds, the enemy takes the difference in damage AND is [b][i]trapped[/i][/b], unable to ESCAPE but still able to attack.

Grave Plot: {requires Snakebite}  Brick opens a large hole to trap a single opponent (attack versus defense) if he succeeds, the enemy is unharmed but [b][i]captured[/i][/b], unable to ESCAPE or attack.

Tombstone: {Requires Grave Plot} Brick opens a large hole to trap a single opponent (attack versus defense) if he succeeds, the enemy takes the difference in damage AND is [b][i]captured[/i][/b], unable to ESCAPE or attack.
