Cobweb Cavern is an additional dungeon for the Heroica game. We use it with the "Heroica: Adventure Awaits!" variant.
About this creation
Overview of Cobweb Cavern.
The rules variant we use with this dungeon, including the rules on moving on the Cobwebs, the boulder trap, the Magic Gem, etc., can be found here on Boardgamegeek..
[For the purposes of the Custom Board Contest, I've put a modified version of the special rules for this dungeon in square brackets here, so you can play this dungeon by using the regular Heroica rules.]
The Secret Door in Waldurk Forest that leads to Cobweb Cavern.
[To open a Secret Door, a Thief or a Wizard must roll a Shield in front of the door. Or, any Hero with a map (the white squares on the desks in Fortraan) can open the Secret Door automatically.]
Approaching the giant skull which forms the outside of the cavern. In case you're wondering, it's a Rock Panel Skull which we found in our collection and built this dungeon around.
Landing on the Treasure Chest triggers the Giant Boulder Trap which lurks behind the skull's eye.
[The Giant Boulder will land on the space before the Treasure Chest. Run! After that Player's *next* turn, it moves forward two spaces. It automatically moves 2 spaces after that Player's subsequent turns. If it reaches a Hero, the first Hero it squashes loses 3 HP, the next 2 HP, and the third 1 HP. When it reaches a corner, roll a die. On a Skull or Sword/Skull roll, the Boulder ricochets and continues to roll after the Heroes. On a Shield or Sword, it turns into a Rock Pile.]
The Giant Boulder is rolling toward the Barbarian. Run, Barbarian, run! It's mandatory to sing the "Raiders" theme as the Boulder rolls forward.
Looks like the Barbarian ran fast enough, and the Boulder smashed into a Rock Pile. Now he's got to climb the rope to get inside.
Inside Cobweb Cavern. Heroes must move around the webs clockwise or counter-clockwise. If they fail to land on a post, they're stuck in the web! Also if the web is overloaded with Heroes, they will fall into the poison river beneath them.
[The rules for moving on Giant Cobwebs in Cobweb Cavern are different from normal movement. You get no movement bonus from any item on the Cobweb. You start on a Non-Sticky space (antenna top). When moving, must move your full roll, either clockwise or counter-clockwise around the web. (So if you roll a 3, you must move 3 spaces.) Moving from one Web to another counts as one space. You cannot move onto the center of the Web. If you can't end your move on a Non-Sticky space, land on a Sticky space. You are Stuck. Lose your next turn. On the turn after that, get Unstuck -- move to the nearest Non-Sticky space on the web, and end your turn.
[The Cobwebs can only bear the load of one Hero. If a second Hero lands on the same Cobweb, both Heroes fall into the poisoned river below. The Heroes lose 2 HP, and the river carries them back outside the cavern. The Cobweb remains, along with any Spider that was on it.]
The Barbarian has made it across the webs and is ready to fight the Spider Queen.
[The Spider Queen has Strength of 5 and a Special Defense, "Web Spin." If you roll a Shield and attack the Spider Queen with a Ranged Attack, immediately roll again. On any roll but Skull, your attack succeeds. On a Skull roll, the Spider Queen has interrupted your attack with a Web Spin. The attack fails, and you lose your next turn as you free yourself from the Web.]
The Spider Queen guards a Magic Gem -- the Gem of the Spider's Eye, which gives +1 to defense. The Hero who defeats her also gets an Enchanted Bow as loot.
[A Hero with the Gem will take one less damage from any Monster's attack. The Enchanted Bow works like a regular Bow, but the Ranged Attack can be triggered with either a Shield or Sword roll. A Ranger with the Enchanted Bow can use the Ranged Attack on any roll except Skull.]
The passage out of Cobweb Cavern -- it's a secret one-way door at the end, so no short cuts that way!
Congratulations. You have been awarded 3rd place in the fifth Heroica custom board contest (February 2012). I was particularly impressed with the creative use of bricks and gameplay rules of the board.
