Senpou Temple (GS)

From the first sculptor's idol in the starting area, continue up the trail avoiding/killing the monks along the way, until you reach the first large building. You can only enter from the opening on the ceiling so use your Grappling Hook to reach it.

Carefully take out the critters and slowly go downstairs. There are a lot of monks here, including a large enemy so deal with them at your own pace.

Once the area's clear, you can now loot the Gourd Seed in front of the undead monk. Make sure to pick it up quickly since this one will continue spewing off insects. You don't need to waste your effort killing it since it will just resurrect after a short while and you won't earn any EXP from killing these monks.
