The Staff of Aesculapius

The Staff of Aesculapius is the healer quest artifact. It is neutral for wishing purposes. Its base item type is a quarterstaff.

It deals double damage to all monsters without level drain resistance, drains levels from them, and also gives hungerless regeneration and protection from level-drain. If #invoked, it heals half HP damage, cures sickness, unblinds, and unslimes.
