Other Weekly Quests: Farming gold and lesser materials

Tuesday: Fire/Water/Thunder Mask
25 energy / 10 levels.  Guaranteed drop off of boss.
Plays out mostly like a mid-level normal quest.  Stage 9 always has a holy and dark mask.  Note that these are the only quests where one can safely farm dark masks.


Wednesday: Spirit Tribe I
10 energy / 5 levels
For farming those low level enhancer cards (i.e. ones needed to evolve other cards).  Drop rates here are higher than normal quests.  This one has those winged freaky tentacle monsters and chaos (eggs).


Thursday: Giant Tribe I
10 energy / 5 levels
For farming goblin+ and holy chaos (eggs).


Friday: Spirit Palace
10 energy / 5 levels
For farming non-winged freaky tentacle monster evolution cards.  Also a holy mask at the end.


Weekend: The Heritage of Satan I, II, III
10/15/20 energy / 10 levels
For farming dark coins.  AFAIK, only dark coin cards can drop.  They have a high, but not guaranteed drop rate.  The other enemies seem to be random assortments of enemies you'd come across in normal questing, but of varying difficulty.  Dark coins sell for 5000 gold a piece.


Weekend: The Heritage of Satan IIII (fail at roman numerals lol)
25 energy / 10 levels
For farming dark coins (level 2 and 3).  It is not mentioned in the quest title, but HOLY OR DARK DIAMONDS CANNOT APPEAR, so keep that in mind when making a team.  This also means only 4 types of diamonds can appear, allowing some ludicrous combo chains (my personal best is a 25x combo that instantly cleared stage 9). A mono-elemental deck with stacked 200% damage may result in some hilarious damage counts.  Dark coin level 2 sells for 50000 I think, and level 3 is for 100k.
