Sinkholes

Sinkholes is a Dungeoneering Distraction and Diversion released on 5 February, 2013. It takes place outside of Daemonheim, in resource dungeons that were once used by Bilrach as storage rooms - these are scattered across the world and Gorajo have since found them.

The activity can be started by talking to Talsar located in the Daemonheim camp. He will give the players information about himself and the location and time of the next sinkhole due to emerge with each one due every 30 minutes, however you can only play twice per day, if an attempt is made to play a third time, the player receives this message: "You can only enter a sinkhole twice a day before it becomes unstable. Return tomorrow to play again."

He offers the players a teleport to the expected sinkhole location when nearer the time.

The sinkhole's themselves comprise of a dungeon like those found within dungeoneering training. The rooms contain low levelled monsters to be defeated, resources to be harvested and exploratory totems found in each room. The players enter the sinkhole and are grouped into groups of 5 before the activity starts. The main room offers Gorajo armour for all players in the 3 triangle classes for the dungeon.

The ranking system is based on the amount of the above the player has collected and deposited into the select few bankable locations. When a resource or monster totem has been banked it is ticked off on the top left screen tracking the progress of the group.

After the activity has been completed by all targets being met, the prize stage appears lining the players up based on their rank gained from score in the activity. More kills and resources banked gives a higher score.

The players then take it in turns to use special ability cards, which are found within the dungeon to do different abilities in obtaining a better prize. Some opponents steal the prize and replace it with yours, some cancel the opponents' card move. There are 11 of these cards in total.

Rewards vary from lamps in dungeoneering experience, dungeoneering tokens, and cosmetic Gorajo armour similar to the ones you wear in the activity: the Hoardstalker outfit.

Trivia

 * At release they were scheduled to take place every two hours, however this was changed soon after to every half hour instead, just 15 minutes before the second sinkhole formed.
 * The sinkhole update is a competitive version of dungeoneering.
 * There is currently a bug which may prevent you from using a preening ibis card, as it does not show up to be selected.
