What exactly is cheating about EQVE? It's just DUST that doesn't burn. And it's not indestructible like people say. although, it won't block pressure ... i'm not sure if you can block pressure with just powders, since powders are supposed to move around with pressure.

Edit: but BVBR might do something, it absorbs both heat and pressure

i'll edit that later to remove it then ... because it's untrue. EQVE has exactly the same properties as DUST, except it won't melt, burn, or anything like that. It's even the same color as DUST. EQVE will be destroyed by BOMB, ACID, DEST, SING, and many more elements.
