Powerhungry Perk

Instead of losing 1 food point every minute, you lose 3.
Sometimes you lose 3 at minute mark and one later, appears to be a bug with no interest to fix.

There is no perk removal stone in game or in shop nor is there likely to be one.

You cannot take both Powerhungry and Powersaving.
Some things, such as Harvesting also take food to do well. This loss is in addition to normal food costs of varying activities.
The Powersaving cloak will still work, no food deducted so long as you are not harvesting, reading, or healing (material or mana).
