Okay so I guess I haven't received enough criticism for posting on this message board about the bat idol so I'm back.
My party has reached the colony and is preparing it for the attack from the Crimson Fleet. My character is an elfin rogue with a decent trap building modifier and a fairly decent use magic device modifier. I want to set up traps around the perimeter of the colony and dig a tunnel that goes from the center of the town to the caves just outside the town. I am new to D&D and I am not quite sure how to go about doing this or what types of traps I can exactly build. My DM has told me we have two months and Lavinia's resources to work with. Are there any types of limits to traps or elementals that could build tunnels? Any advice will be greatly appreciated by our group as we are all novices. Thanks!
