A
shatter spell will destroy worn armor as long as it's not magical.
Rusting grasp specifically degrades or destroys armor.
Back in 3.0, I used
polymorph any object to transform +5 full fortification full-plate armor on a storm giant into green slime. Now the spell doesn't work on magic items.
When I was playing a Living Greyhawk adventure, a fellow player had his character's armor destroyed with
shatter. Normally this is something that simply sucks for the player, except that he had
just spent over 10K to craft this full plate mithral armor, which required him to burn a regional campaign favor to simply get the mithral. It was probably the most expensive non-magical item of gear a player could have, which he would then have been able to afford to magically enhance after this adventure.
At this point the player was near campaign-suicide. But all was well when I told him that I could cast
make whole and that would restore his armor completely. This was especially significant because the armor would have been
gone from his character if I wasn't able to restore it by the conclusion of the adventure.
Nice to know I can make a positive difference in the world. Well, at least in a game world.
