Although this isn't actually an elemental temple, I decided to make this guide since it is in a way the first part of the Lightning Temple.
LEGEND: A green circle means there is some sort of goodie in a chest, a black one means that there are monsters. White lines are where you should walk.
NOTE: If there is a place in the map where I haven't told you to go then that means there are no chests there.
A. Go to Henesys. Take the portal in the top right corner. Then take the portal in the top right corner again. You should now be in "Golem's Temple".
B. From this point on it's pretty straightforward, just follow the pictures exactly. Each picture picks up where the last one stopped, so try looking for some sort of land mark to get your bearing.
C. Follow the picture.
D. Follow the picture.
E. Follow the picture.
F. Push the rock forward a few spaces by pressing enter while in front of it. Then walk around the rock.
G. Follow the picture.
H. Follow the picture.
I. Follow the picture.
J. Walk all the way to the left and turn around in the part that I omitted.
K. Again, push the rock forward a few spaces by pressing enter in front of it, then walk around it.
From here just walk straight forward and go into the stairs. That's it, you're in the Lightning Temple!
Always press enter at the green chests, they give you white potions or phoenix feathers, items that could be helpful in future battles!
If you are a low level press enter at the black circled chests, they'll give you a chance to gain some experience. If you're a high level then don't, it's simply a bother.
I suggest that you follow my Lightning Temple Walkthrough
when you finish this one.
