If you dont mind, I am going to grab this part here :

Hell Mephisto has 94,320 life in a 1 player game. Assume he has ~50,000 life after
Static Fielding, your merc tanks, and you�re usually �sweetspotting� (orb explosion inside
Mephisto's graphic).
1) 20 Frozen Orb/Cold Mastery minimum band: 267 dmg
-115% cold resist modifier vs. Mephisto�s 75% cold resist: 372 dmg
imperfect 12-shard �sweetspot� hit: 4,469 dmg
50,000 / 4,469 = ~11.18 casts to kill
2) 20 Frozen Orb/Ice Bolt/Cold Mastery, minimum band: 366 dmg
-115% cold resist modifier vs. Mephisto�s 75% cold resist: 512 dmg
imperfect 12-shard �sweetspot� hit: 6,149 dmg
50,000 / 6,149 = ~8.13 casts to kill
Basically, you waste 19 points in Ice Bolt to save yourself 3-4 casts of Frozen Orb to kill Mephisto.
And stick it into another post elsewhere for easy reference. If this bothers you, just let me know.
