Temporary Camp or shelter using Powers

Cooling things down is harder. The GM might let you pull off something similar to the firewall above, using either non-incendiary burning damage (used for some magic/superscience cold attacks) or FP damage with the Freezing Hazard, but that's a bit of a stretch. There might be some tricks with airflow that would let a skilled builder make a building that stayed cool passively, but I kind of doubt it (the only cooling option mentioned in LTC3 is an expensive method of keeping a building water-cooled, which isn't something to rely on here).

A burning attack wall is actually a very creative idea! I think I have a few new ideas I can use from this thread. Thank you everyone.

Any ideas here?

The Accessory perk, treated as a magical, psionic, or otherwise Powered ability, could be used to generate a shelter that is equivalent to the sort of tents that are easily available for purchase in the setting (so, probably provides little or no DR, and takes about as long to 'put up' and 'take down,' though perhaps you can give the 'take down' command and then walk away).

Just remember that a burning wall is permeable, so you might be able to use it for heat or cooling based on the special effect, but it won't keep things out that are not obliterated by the damage.
