Golden Sun: The Lost Age/Suhulla Gate

Suhulla Gate
Head left and up the stairs, then up the next set...then the next set. Here you will encounter another Ruffian. Do the same as before and proceed heading left, once you reach the vines climb down the first set then the second and head towards the cave door to find 3 Ruffians. I suggest using Flare Psynergy with Jenna and then normal attacks if there are any Ruffians still alive. Might also be wise to use an Herb aswell. Now enter the cave door.

Inside the Cave
Follow the cave path and head down the stairs then into the entrance that leads downstairs. In this room walk over to the purple stone lying on the ground, once you get near an enemy will jump out of no where -- a Punch Ant. Use Fume on it and the Punch Ant should go down. Kraden talks to you and then grab the Psynergy Stone which restores all your PP. Continue following the path until you reach the exit of the cave.
