Recently on my mind an idea that players who are in the Altar of ennoblement can by clicking on the desired statue had a choice
meditation or demeditation (or something like that) and with the passage of time (exactly as in the case of meditation) stamina will be
converted into liquid essences which can be closed in a bottle with the appropriate value.

Next idea is one of the events in which the player with the appropriate amount of stamina bottle's can exchange them for a scroll MP
dungeons or lucky star in jewel huntfor example and similar attempts in various "exchange"

I hope that I'll see in wartune my idea XD Thank you and best regards.
