Dragon Information
as appears in dragon.inf
Every breath weapon does 1/3 of the monster's current hit points,
except lightning, which does 1/4.
Acid damage is then halved if you have any armor to corrode, or
divided by 4 if you have resist acid and some armor.
Cold or fire damage is divided by 3 if you have permanent resistance
(from a ring, armor, or weapon) or temporary resistance (from a potion
or priest spell), and by 9 if you have both.
Lightning damage is divided by 3 if you have resistance.
Gas damage always has full effect.
- Ancient Multi-Hued Dragon: (40/276)
- 2080 total hit points
lightning: 520/173
acid: 693/347/173
fire/cold: 693/231/77
gas: 693
Even a 40th level half-troll warrior with 18/100 constitution,
heroism, and superheroism would probably not have 693 hit points.
Thus you must never fight AMHD's if you are giving them any
opportunity to breathe on you. I don't like to go down to level 40
unless I have 231 hit points and resistance, so that I can survive 4
out of 5 breaths from off-screen AMHD's.
- Ancient Green Dragon: (39/269)
- 720 total hit points
gas: 240
- Ancient White Dragon: (38/263)

- Ancient Blue Dragon: (39/268)

- 840 total hit points
fire: 280/93/31
- Balrog:
- 3000 total hit points
fire: 1000/333/111
Thus a mage with less than 333 hp can be killed by one breath from the
Balrog, before he gets a chance to drink invulnerability potions. For
a mage to get 333 hp, he must be human, and he must use the grape
jelly trick.
