It’s not a Pie, it’s not an Orc! It’s a Random Trap!

Posted on Updated on

We all have a need for Traps, and sometimes we forget that room XX has a trap in it. And yet there we are wondering what the stat block for that trap is going to be. Sure you could recycle that trap from room YY but then the characters are going to think the dungeon is incredibly predictable. And the goblins from room ZZ are going to back again in room AA. But we don’t want them to know that yes, in fact the dungeon is symmetrical and yes, the same goblins are in AA as are  in ZZ.  So when you want to confuse yourself, and the players, well it’s time to drop some dice and roll up a random trap!
