help getting the skull key

[ladylove2fly]

I have gotten to level 1 on the three quests in Undead that give out the skull key, but haven't gotten enough keys to finish the last two quests!
I go in and spend all 130 energy points (now 3rd time) redoing quest and have only been given one key!!! Anyone have any tips on which quest is best to redo--or is it all a chance crapshoot? Been working on this for two days trying to figure it out.
If I don't there will be no Lotus for me!!! :0 Maybe that's not such a bad thing...she is nasty...
