I went inside of the cave and collected my divination exp like normal, but it didn't give me the tainted souls like it usually does. I have about 350 and would probably have gotten to 500 for another override. Please help!!
The Cavern of Tainted Souls was a limited time event. Whilst you can still use any sparetickets to enter the portal, Essence was only available between 00:00 on the 8th February through to 23:59 on the 12th.
As you have some Essence left over, I'd recommend converting them to exp by left clicking them -they'll be removed on the 25th of this month.
This thread is now closed as it is very old and the question that was asked has long since been answered, and the thread is not regarding an in-game player hosted event.
