In a game session last night during a RtL campaign, our Overlord had played a treachery card that lets him place an ice marker on the board.
The situation was we were in the second area of the Legendary Area (the fools rapids) and he placed a 2x3 ice marker on a a square beside the glyph in the center of that area. The triggering square.
He tried to place the 2x3 marker so that it would go under the glyph that was there, I said it was not legal, but reading the card I could not find any sort of rule to back it up in the FAQ or elsewhere as a glyph is not considered to be an obstacle.
The exact text on the Frozen Path card:
Play this card when a hero moves into any empty space. Place any available Ice marker so that it overlaps that space, is completely on the board, and isn't overlapping any obstacles.
That hero is affected by the Ice marker as if he just moved into that space.
Everything was legal about the trap he placed, except that he had placed it under the Glyph in that area which I am not sure about.
