I was fighting and fighting and fighting and somehow (don't ask me how ... i'm no mage and don't have stuff like that) i got a nice buff which drains 1 mana per 4 turn. After some time my mana was running very low (i got 65 mana and 8 of these are from the buff) I was under 5 mana and after pressing Save&Continue my Mana got filled up to 12. And i was able to repeat it even after completly closing DoD. most likly related to this bug - http://community.gaslampgames.com/threads/1-0-8-hotfix-saving-reduces-hp.1488/ - just in reverse Save attached
You must have drunk a Pan-Galactic Gargleblaster, which gives you the Syzygy buff (identical to the Syzygy spell in Astrology). You can tell DoD isn't a "proper" Roguelike because you drunk something without knowing what it did, and yet you are still alive.
