Compact (Psionic)

With this power a psionicist can take any nonliving material and compact it into a smaller size. The material retains its original mass, but its substance is compressed. Each use of this power can compact 10 cubic feet of material into one cubic foot of space (volumes smaller than 10 cubic feet are reduced by nine tenths). The material can be gaseous, liquid, or solid, and reacts to temperature changes normally while compacted. It will remain compact for 24 hours. Then it quickly expands to its original size, exerting tremendous force.
When expanding, the material forces its way around existing things. For instance, an expanding boulder on a surface of sand causes no damage, but compacted water poured into the cracks of stone severely damages the stone when it expands. If carefully applied, each cubic foot of compacted materials can cause as much as 25 structural points of damage on expansion. A creature that ingests compacted materials takes 1d20 points of damage per ounce taken in when the material re-expands. Expansion is quick, but not explosive.
As a side effect of compaction, the material receives a +4 bonus to all item saving throws.
Power Score — The material is actually compacted by 20 times instead of the normal 10 times.
20 — The material does not compact, but instead becomes extremely hot, possibly destroying itself and causing burn damage to those around it.
