Barricaded Towers are Objects.

These towers are found throughout the fortified surface areas of Act Five. Towers are harmless on their own, but become troublesome when Demon Imps teleport into them and begin to use their mounted Inferno skill. The tower must be destroyed to stop the Imp's attack, and these towers have a lot of hit points, especially on Hell difficulty.

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

No offense of any kind. Faildog!

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.
