Encounter Map- The Cave of the Sporelord

[Neuroglyph]

This is an encounter map that I just completed for a new 4E supplement called "Kill or Be Killed".

Background:
After climbing up a steep cliff face over a nigh bottomless crevice, you come to a massive cavern. Here a subterranean river once ran, to pour over the cliff and down into the depths below, but something has nearly dried it up. Patches of mud and pools of water are all that remain of the ancient river.

The cave is alive with giant mushroom growths, many of them glow pale in the darkness, casting the shadows of stalactites and stalagmites dimly around the chamber walls.
In the distance, a huge pile of boulders moves in the wan light. It rises to become a man-shaped form, and it fixes you with burning orange eyes, filled with hate.

The squares containing stalactites, stalagmites, rubble, mushrooms, and mud are all difficult terrain, and some of the mud and mushrooms actually are dangerous hazards, but of course, it's often hard to tell what is dangerous and what is not before it is too late!
