So this is 1 player game Berserk Barb right? Not Players 8 or full group run?
Berserk Barb that wants highest Magic Find and uses the Find Item Skill right?
To my understanding, Teleport can be used even if your character is frozen (unless changed) because it is not movement, so CbF is not needed... however, you need to research this for yourself because I may be incorrect. However, if you are wanting to use an item with CbF, then you should use the Ring Ravenfrost instead of a Cham rune, reasoning is simple: +Attack Rating, + 20 Dexterity (AR again + less points added to dexterity wielding Phaseblade) ... a Cham can not contribute for AR / Dex (note more stat points for Vitality = more life)
Remember, Berserk doesn't Leech Life or Mana and is bad vs Magic Immunes, thus you should use 1 base Concentration skill to deal with Magic Immune and also be able to Leech.
Magic Find diminishing returns start at 100% Magic find and the curve deteriorates the more you have, so people prefer 250 to 300%, above this is counter productive with Killing speed and more runs to counter it. My personal opinion is just 100%, I also like to find runes where Magic Find has no bearing on their drops.
Two Helms:
Arreats with 20% IAS (+ your PB Grief) should be ideal... also added strength for damage, just need to Ral rune it or use a Fire res jewel with another mod)
Shako, since you want mf, however you will need to use another IAS item, maybe Highlords Amulet.
Both of these Helms have +2 All Skills, this means an additional 4 Skill points to 1 point into a skill, so your Find Item skill of 1 base point will be 5, thus higher % chance to Horck corpses (increasing % chance), and since you are using Enigma, that means another +2 All Skills.
Now that is +6 all skills to every skill you have chosen, including Resistances, Weapon Masteries etc.
Now, I mentioned Highlords, that is also a +1 All skills, yet it has 20% IAS and Light Sorb ... depending on what helm you choose, you may want to use Maras or a +2 Barb Skill with FCR & MF
Reaching 105% FCR comes from Switch + Belt or Ring &/or Amulet.
Options given is 2x Wizzy + 10% FCR ring as switch
Arachs has 20% FCR & +1 Skills ... so do you need the FCR ring? No, you could use 2 Ravenfrost or use a 40% MF ring, actually, even a +35% FCR Spirit with wizzy = 85% FCR and Arachnids = 105% FCR and forget about the 10% FCR ring. On top of that, the Spirit Monarch has + 2 Skills aiding Enigma Teleport and other skills for barb for defense etc.
It all boils down to how to excel the build, as for more MF, maybe someone should teach you the diminishing returns a bit better... however this is a P1 build, of course you are going to kill fast, and with +X All skill items, you also increase your Attack rating and resistances for a Barb build, especially a Berserk barb that uses Battle Orders etc.
