In Diablo II: Lord of Destruction v1.10+,
Coldworm the Burrower has the following hit-points in a solo single-player or Ladder game:
Code:
DIFFICULTY HIT POINTS
__________________________
Normal 228- 372
Nightmare 5,721- 7,020
Hell 27,200-33,382
More generally, hit points are calculated using the following formula:
Hit Points = [[[MonLvl * MonStats/100] * ((1 + Players) * 0.5)] * Special]
MonLvl is the entry in the L-HP column of MonLvl.txt for the relevant difficulty for a particular level, MonStats is the entry in the MinHP and MaxHP columns of MonStats.txt for the relevant difficulty for a particular monster, and Special is the multiplier for the relevant difficulty for a particular class of monster:
Code:
MONSTER NORM NIGHT HELL
____________________________________
Minion * 2 * 1.75 * 1.5
Unique * 4 * 3 * 2
Champion * 3 * 2.5 * 2
Possessed * 6 * 5 * 4
Berserker * 0.75 * 0.625 * 0.5
The monster's base level is used when selecting the relevant value from MonLvl.txt. According to SuperUniques.txt, Coldworm is maggotqueen1, which is the Id used in MonStats.txt. Note that the Unique hit-point multiplier doesn't apply to monsters that get no other Unique modifiers in Nightmare and Hell i.e.
Blood Raven,
The Summoner,
Izual and the various incarnations of the Act bosses.
Normal
Base monster level is determined by the Level column of MonStats.txt in Normal, so Coldworm is level 11 in Normal.
Code:
HIT POINTS MONLVL MONSTATS BASE UNIQUE TOTAL
_________________________________________________________
Minimum [36 * 159/100] = 57 * 4 = 228
Maximum [36 * 259/100] = 93 * 4 = 372
Nightmare
Base monster level is determined by area level in Nightmare, unless the monster type is a boss. Sand Maggot Queens aren't bosses, and according to Levels.txt the Maggot Lair Level 3 is level 46 in Nightmare.
Code:
HIT POINTS MONLVL MONSTATS BASE UNIQUE TOTAL
_________________________________________________________
Minimum [867 * 220/100] = 1,907 * 3 = 5,721
Maximum [867 * 270/100] = 2,340 * 3 = 7,020
Hell
Base monster level is once again determined by area level, and according to Levels.txt the Maggot Lair Level 3 is level 85 in Hell.
Code:
HIT POINTS MONLVL MONSTATS BASE UNIQUE TOTAL
_________________________________________________________
Minimum [6,182 * 220/100] = 13,600 * 2 = 27,200
Maximum [6,182 * 270/100] = 16,691 * 2 = 33,382
Off the Ladder but still on Battle.net, hit points are calculated using the HP columns of MonLvl.txt. These are usually quite a bit lower than they are on the Ladder and in single-player. There may be differences in Classic as well.
Since monster level is determined by area level in Nightmare and Hell, the hit points in this Wiki and the Arreat Summit will only be accurate for Normal (at best). For example, in Hell the Fallen (fallen1) of the Blood Moor (level 67) have 1,028-2,261 hit points, while those of the Underground Passage Level 2 (level 83) have 1,488-3,273 hit points. Fallen also spawn in six other areas of Act I, each with a different level. This will also affect their damage, experience, Attack and Defence Ratings.
