I came up with this idea in the thread about SB items, however I thought it might be worth posting it in its own thread. It would essentially be a new option in the explore and would hopefully help remove some of the SB out of circulation to help keep the economy stable.

The Wishing Rock

Once or twice a day sacrifice some SB to the Wishing Rock and perhaps your wishes will come true. The fee should probably be around 50-100 SB perhaps even more. You could wish for several things, which will be listed below.

I'd say the odds should be reasonable, perhaps either 1 in 3 for something good, 1 in 6 for something bad and the rest of the time nothing or so half the time you get a good result, 40% of the time you get a neutral result and 10% of the time you get a negative result. [Alternatively the only 'bad' result would be no effect; although personally the gamble for a negative result would make it more interesting in my opinion] It could be used by any lion, the effects would be applied to the lion who used it

Power A good result would be up to +3 in a random stat or skill for your lion, a poor result would be a loss of a random stat or skill.
Energy A good result would be up to 30% energy regained, a poor result would be a loss of energy (or resetting the energy regaining timer if you are at zero)
Health A successful wish would grant an extension of up to 3 months of life to your lion (or making him/her younger, if it would be too difficult to have a varying age of death). A negative result would be taking some months off his/her life span (or making him/her older if its too difficult to have a varying age of death)
Food A Successful wish would grant several random carcasses and/or refill the hunger bar. A negative result would make your lion hungry or reduce the amount of days left on some carcasses in your hoard
Amusement [lioness/cub only] A successful wish would raise mood or grant some toys. A negative result would make you loose mood.
Wealth A successful wish gets you 200 SB. Suggested by Sainler (#11215). This one might be hard to have a negative result because if the game deducted SB it could result in a negative SB balance so perhaps a 'negative' result would be no SB and a positive result would be any SB up to 200 SB so that some of the time your net change would be a loss (but not the full 100 SB)

Another suggestion by Summer's Eve (#8345) is to combine health and power with a good result being increasing the level, freezing ageing for a certain amount of time or adding a random stat gain (possibly for a limited amount of time) with a negative result being a loss of a level; temporary removal of stat/skill for a certain amount of time or being unable to gain stat/skill for a certain amount of time.

Taking in account a couple of the comments about having a rare prize that might encourage people to throw SB at the rock, there could be a rare prize only available from the wishing rock. You could win it regardless of which wish you chose, but the odds of getting it would be quite low
