Baal's beam is a single missile that deals 512-544 magic damage on Hell. But since your Magic Resist is -100 there (caused by the difficulty penalty), it will deal 1024-1088 magic damage. Like anything else, this missile can crit for 2048-2176.
MDR will reduce its damage, but since it is only one missile, MDR gets applied only once to this massive damage.
After MDR has been applied, ES will reduce the remainder of the damage (but not before the beam takes 50% of your current mana!).
The stuff about Laying of Hands and 4-frame hit recovery were all myths unfortunately, none of that will help you.

Also heißt das:
mit 2200 Leben plus Magic Damage-Reduce und Energieschild bei der Sorc kann man EINEN solcher Hits aushalten. Nahkämpfer mit weniger Leben sollten sich also an diesen Werten orientieren und +Life-Ausrüstung anziehen und Lebenszauber ins Inventar legen bis sie den angegebenen Wert erreichen.
