It's just that the old 4e rules tell me I'm a bad DM for doing that, and tell players I'm a bad DM for doing that.
Anyways, what was wrong with the residium being found in the stomach of the rust monster? Thats perfectly logical!
It makes sense for something to be there. But what's at stake? Why negligible loss? If the dog eats my homework, I'm expecting to get it back as poop, not something I can remake into something equivalent to (or even equal to) my homework.
Is residium a new buzzword for oxidized ferrous metal?![]()
Well, it is a magic weapon. The magic has to go somewhere, right? I mean, when a rust monster eats my +5 magic sword of legend, there are only two possible places for the stored up magical energy to go: either the it remains in the oxidized pile of scrap that is left of the sword, or it is released all at once and the rust monster spontaneously explodes like a spectacular firework. Or maybe is polymorphed into a gerbil. I guess that depends on what kind of legendary sword it was.
