Bat Demon

Bat Demons are Animals.

Bat Demons are small, winged, aerial melee attackers reminiscent of the Blink type monsters from Diablo I. Unique amongst Diablo II monsters, bat demons hang from the ceiling (or thin air, on outdoor levels) and only drop down once a character is within their melee attack range. They can be targeted while on the ceiling, and can be hit by ranged attacks, or will drop down once a character is nearby. Bat demons are fond of flying away when they are low on hit points, and must be killed quickly, or pursued to their new perch.

• All values are listed by difficulty level: Normal / Nightmare / Hell.

Statistics

• The TC/Rune drops listed are the highest Treasure Class/Rune Group a normal monster of that type can drop.
  • TC Champions and Bosses can sometimes drop from the next higher group.
  • The max TC/Rune possible may depend on which level a monster spawns in, and can be lower than the maximum. See the item calculators to ascertain precisely what a monster from a given area can drop.

Defenses

• Regen Rate tells what % of a monster's hit points are recovered per second. Standard is 1.2/sec.
• Blocking values are assigned to every monster in the game, but the ability is seldom enabled, so most monsters can not block (Hence the blocking % given on most Diablo II monster pages, including Blizzard's, is inaccurate.) When enabled, blocking tells what % of successful, blockable attacks will not damage the monster. Monsters need not carry a shield to block.
• Drain Effectiveness tells what % of a character's mana and life steal apply to that monster. 100 is all, 0 is none.
• Chill Effectiveness tells what % of a character's cold length applies to the monster. 100 is all, 0 is no freeze/chill at all.

Resistances

• Resistances over 99% are listed as immunities and monsters will take no damage from that type of attack.
• Immunities can be "broken" by skills that lower resistance, if the value drops below 99%. See the Resistances page for more details.
