I'm not sure if this belongs in exploits(More like clever use of game mechanics?), but I'm posting it here anyways.
Basically If you die on the High priest Venoxis fight In Zul'Gurub you can use the environment around you to get back into the room. Now this is not supposed to happen due to the fact there is a massive green thing covering the door.
OH no I died on High priest Venoxis and we don't have a battle res! What to do?
Release and run back in. Go run up to this area:
Use the box next to the tree stump to jump up onto the root such as this:
The next place you want to get to is the part that I have circled. Now I suggest dismounting and then jumping over to that spot. If you go too fast, you'll miss the jump and end up in the water then just die again. You'll end up looking at something like this:
Now just mount up, and jump onto the land down there. Be careful, he might have the maze going and you could easily jump into that and die again. However, if you pull this off it could prevent a wipe (Hey it could happen maybe?).
If the images are small sorry, I didn't want to stretch out the forum :P
