Templates for terrain effects

[Firebeetle]

I'm working on making templates for the various "terrain effects." Powers like "Icy Terrain" that leave an effect that lasts until the end of the player's next turn (or similar duration.) I've been trying to compile a list, but it's been hard and I'm afraid I'm missing things as I slog through the Compendium. Could folks here help by listing powers. Feel free to list source or size. Thank you.

List so far:
