* 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.
