Elite dungeon bonus schedule.

Full credit and thanks to yuenyip for finding this info and translating it from Chinese and to Trendz for collating it.  I was just the copy & paste monkey....   

There is a schedule of bonus periods for various dungeons over the course of a week.  For the Elite dungeons the period seems to start at 10pm GMT / 2pm PST and lasts for four hours.

The bonus period offers a benefit based on the nature of the dungeon:

If the dungeon contains one or more 12 AP Elites the drop rate of their full card is at 1.5x normal
If the dungeon does not contain a 12 AP Elite the AP cost of the dungeon is halved (5 instead of 11 AP)

This is the schedule:

Monday
Howling Cave, Zul, Psychic

Tuesday
Death Mine, Malador, Blackrock Upper

Wednesday
Silverfang, Dire, Labyrinth

Thursday
Thornfen Kraul, Temple, Crypt

Friday
Scarlet, Blackrock, City Wall

Saturday
Thornfen Downs, Blackrock Lower, Mausoleum

Sunday
Alteman, Seturmeon, Dark Hold


You can use this info to hunt 12 AP Elites with 150% chance of a drop or to hunt Rare Weapons (to upgrade your initiative skill feeder cards to green+) at half cost.

Thanks for the info
