Character statistics are the most important way to gauge the overall health of our hero. Whether Γκέραλτ lives or dies is governed by his Ζωτικότητα, but Ανθεκτικότητα and Τοξικότητα play their parts.
Ζωτικότητα 
[]
Ζωτικότητα (sometimes referred to as "hit points"), indicated by the red bar, drops as damage is incurred. If the red bar reaches zero, Γκέραλτ dies. A grey screen and (very) audible heart beats warn you of dangerously low vitality.
Vitality is restored over time, very slowly though. Recover more quickly by meditating or drinking potions.
- Developing Δύναμη is paramount here.
- Χελιδονιού accelerates its regeneration.
- Any Rubedo-enchanced potion will also help.
- White Raffard's decoction gives an instant boost, but is highly toxic.
- Φαγητό provides 9 minutes of "weak" vitality regeneration each time an item is consumed.
Ανθεκτικότητα 
[]
Γκέραλτ's Ανθεκτικότητα, indicated by the yellow bar, drops each time he uses a sign. He can not cast signs when his Ανθεκτικότητα is too low. In fistfights, blocking also siphons Γκέραλτ's Ανθεκτικότητ; reaching zero, Γκέραλτ can not block.
Ανθεκτικότητα is restored over time. Use potions to help with its regeneration.
- Developing Αντοχή is the basic strategy.
- Κουκουβάγιας accelerates its regeneration.
- Maribor forest significantly increases its maximum level.
- Μη-αλκοολούχα ποτά give 9 minutes of slightly accelerated Ανθεκτικότητα regeneration each.
Τοξικότητα 
[]
Τοξικότητα, indicated by the green bar, increases with each potion consumed. Excessive toxicity adversely affects Γκέραλτ's abilities and may even lead to his demise. When toxicity is reaching a dangerous level, "red sparkles" (blood) begin to appear in the field of view, like Γκέραλτ is beginning to hallucinate. This is generally a very good indication that it is time to detox.
When toxicity exceeds a certain threshhold (around 60-70), Γκέραλτ will lose a sizeable portion of his vitality after drinking a potion. If toxicity ever reaches 100, Γκέραλτ will die on the spot.
Toxicity is reduced over time, very gradually though.
- Διαλογισμός detoxifies completely, usually an hour is sufficient, except for drunkenness, which can take several hours to "cure" see Κλαμάτων των Γυναικών for an instant cure.
- Λευκού Μελιού also detoxifies, but removes all current potion effects as well!
- Ritual of Purification removes all current potion effects.
- The Επίπεδο 5 Αντοχή attribute Potion Tolerance is also helpful.
