Hmm... regarding help with the Oracle riddles... I think that if you would ask for help with the riddles IC, this wouldn't be wrong. Especially if the one you ask is a follower of Zavijah or Achernar. Those two faiths' followers should be supposed to be best at these riddles RP wise, for two different reasons.
- Followers of Zavijah should be able to solve virtually any riddle
- Followers of Achernar should be very close to understand the riddles that the wisps ask, because of their Lord's favour... They are keen to the lands of Death.
Yet, the one you ask has the right to deny his help, to his own reasons... A follower of Zavijah may not want to help you because of your aura eg, or a follower of Achernar would not help you for he wants you to gain knowledge from this experience of Death, and have you for a longer Time in his Lord's lands...
In all ways, I do not see something wrong in asking ICly for help with the Oracle's riddles.
EDIT: P.S. Regarding Quall's post, with all friendly means, posting here what your reply shall be as a warning is decreasing the chance for you to RP.
Let them ask you, and if you feel like denying your help, it may be a chance for you to RP your denial. If you feel like helping them, you may also RP your character's wisdom to find such answers. So, discouraging others contact you for such help is... leak of your IC future response?
