Ahh, the long awaited Lightning Temple Walkthrough! For the most part you can just follow the pictures. Contains spoilers..
LEGEND: A green circle around a rock/chest means there is some sort of goodie inside, a black mark means that there are monsters. Blue circles mean there is nothing inside a rock. White lines are where you should walk, dots represent jumping.
NOTE: If there is a place in the map where I haven't told you to go or I've omitted a bit of guidance, then it's probably a straight path with no or empty chests/rocks.
If you do not know how to get to the Lightning Temple, I suggest you follow my Golem's Temple Walkthrough
A. Enter the Lightning Temple and follow the picture; jump through the mini-islands as represented by the dots.
B. Continue straight up, breaking the rocks in your way. The first rock is empty.
C. The second rock contains a goodie, it should help you later on in the battle!
D. Remember this spot where the 4 paths intersect, it is super-ultra important! For now walk down.
E. Walk up the ladder and straight to your right. The first two rocks you see are empty.
F. The three shown rocks contain monsters, the chest contains a goodie used for creating weapons!
G. All four rocks surrounding the switch contain monsters. Break one. Then, while facing the switch, press enter. A door is now open! Go back until you reach the intersection (in D.)
H. This time walk straight up.
I. Walk through the doorway shown. Up and to your left, again face the switch and press enter. Now go back to the intersection (in D.)
J. This time walk left from the intersection. This part is pretty straight forward, just go to your left, up the ladders and follow the path until you reach the swithc. Press enter and go back to the intersection (in D.)
K. Go back down from the intersection, closer to where you came from.
L. Now go up the ladder and continue on the path.
M. Jump to the other cliff and back. Break through the 3 rocks shown (2 empty, the middle one has monsters). Continue straight along the path down, turn left and walk straight till you reach the switch. Open the switch and walk back to the place with the ladder.
N. Continue along the path shown, it will lead you across a bridge and through the 4 doors you have unlocked.
O. Congrats, at this point you should reach the Temple! You need to solve a code to enter, click here for help.
Save the minute you get into the Temple. Bring lots of pots
Make sure that Zeru isn't equipped with a Fishing Rod or Pickaxe. If he is, equip him with his weapon and save again. (I made this mistake xD)
you should simply use your regular skill, because otherwise it won't work.
Make sure to pot alot during the battle, Reinge is tough! Good luck!
