Potion of ultra healing is a type of potion in ADOM. When drunk, a potion of ultra healing restores the PC's HP. If the potion is uncursed, it tends to restore around 60-80 HP; it has roughly the same power as the Heal spell. Drinking a blessed potion restores HP by a maximum of 333, and raises the PC's maximum HP. Thus, quite counter-intuitively, a blessed potion of ultra healing is roughly equivalent to a blessed potion of extra healing.
