I would like to recommend that when there are no destructible objects present that Telekinesis create a no-collision cube that goes from small to titanic sized based on charge. This object should share every characteristic of destructibles, except for collision.

When the mentalist or another character capable of lifting or throwing this object hurls it at an enemy, it should disintegrate and leave no physics debris behind. If this object is destroyed, it will detonate for (x*(SS1+SS2)) damage against hostile entities.

Alternate implimentation: An advantage is added that makes telekinesis only spawn destructible cubes of varying size depending on charge, with no collision, and a limit of 5 out at once. This would be an attractive option for builds that have enough STR to throw their created weights, or a mentalist who wants this power to play a new way and put objects on the field for use by other teammates.
