Best strategy to finish my grail?

Hi,

Items missing from my grail:

Torch of Iro
Tyreal's might

Entropy Locket

Metalgrid
Cow King's Armor
Cow King's

Boots
Rotten

Fissure + the renewed Rotten

Fissure

If runes :

Cham and

Zod
I don't really count runes.

For MF, I have only been playing Sorc and Warlock, and farm Andy mostly. Do I need to switch to a Pitzerker?

well mathematicaly the best strategy is to farm areas that can drop the highest ilvl item you are still missing but not higher to reduce the pool of possible drops. since you are missing tyraels you are capped out still, but lets say you find tyreals (and any other tc87 item) you would go lower areas. if you only miss a "normal" set (like I think cow kings is?) you would only farm on normal. ofc you always have to take into account kill speed (dmg and monster density), its better to kill 2 monsters with 1/10k chance than 1 with a 1/8k chance if you do it in the same time

cow king

Boots/armor can drop from normal king + minions, 1 in 75

I believe

Torch of Iro and both Cow pieces are preferably farmed in Normal mode. But the rest is still hell, and terrorized if possible. Should I still switch to a Pitzerker and farm pit/terrorized?
