Armor class
Your armor class, visible with the 'SCORE' command, tells you how well-armored you are against the physical and magical dangers of the world. It is a combination of natural intelligence, the protection offered by worn items, and magical enchantments or enhancements. Your AC is also affected by your body position--sleeping characters have worse AC.
The lower (more negative) your AC number is, the more effective your armor will be at reducing damage, as a percentage value, with increasing returns for lower values. Against lesser opponents it may help to avoid being hit altogether. On the other hand, having an AC higher than zero will increase vulnerability to damage.
Hit points
Run out of them, you're dead. All classes gain the fast healing skill that improves passive health regeneration.
Mana
A resource used to fuel most active abilities and spells. All classes gain access to the meditation ability that improves passive mana regeneration, and some classes gain trance which improves it further. Some classes also gain active mana regeneration, such as cantrips and Brawler's Renewal.
Movement Points
A resources consumed when walking from room to room, and fuels some abilities. Walking over difficult terrain consumes more movement points, but this can be mitigated by flying. A few classes gain abilities that improve movement regeneration. If your movement is drained, you cannot walk from room to room.
