to jump on the other person's questions, I have no interaction to collect the glowshrooms... I have opened up the sealed gate and gotten to the pure lake, but there is no dialogue with anyone to get the mushrooms, nor get any amulet.. any advice?
Okay when you get to the bridge, choose "Look for another way around." That should lead you to the cave in order to get the glowshrooms then go to Lizardmen temple n talk to Ortha for the amulet.
You can go to your menu, press on preferences and check unlock on the cheat screen. From there you can find it in I believe in Consumes, that should help ya out.
