Shawn the Excavator's Request

I have a friend who's busy excavating the Excavation Site near Perion. His name is Shawn, and he asked for some help. Apparently he's never seen these monsters before, and they are interfering with the excavating process, and so he has asked me for help in eliminating them. Can you help us out?

I appreciate your willingness to help me here. Before eliminating the monsters, I need you to do something else first. The only way to prevent the monster from ever coming back is to scientifically study the origin of the monster. The best way to do it would be for me to take a look at them myself, but I have so many other researches to conduct that I need you to gather up 5 each of Wooden Board and Slate that Wooden Mask and Rocky Mask possess.

You don't know how to get to the Excavation Site? Go east from here, then go through the portal on the right of the Rocky Road.

I don't know if I've asked for too much... but the monsters need to be taken care of ASAP...

Did you bring 5 Wooden Boards and 5 Slates?

Good job. Now please wait here while I look into these, Wooden Board and Slate.

Please bring 5 Wooden Boards and 5 Slates with you.
