The tanking Necro is...Shaft, SS, 09 Shako. Max block, max DR. In that case, they have lower in vita, since they put lots of point in Dex and Str.

With that build, most necros will have around 900 - 1000 life. (Correct me if I'm wrong...)

With Maxed BS, + lower resist, the necro is good to go. (Load up on Frw tho.)

Cronic recommands "40 small 5% faster run/walk charms", along with boots (30% frw, or 40% if you use Aldur's.)
40x 5% + 40% frw - 5% (speed loss from Shaft)= 235% frw.

Effective Faster run/walk from items = (120 * total FR/W on items) / (120 + total FR/W on items) = X
Faster Run/walk from skills = Y
Total effective FR/W = X + Y

Effective Fr/w from items = ((120 * 240)/(120+240)) = 79.4%.
Y = zero.
X + Y = 79% Effective Fr/w.

Personally I'd go after 10x P/B GC with 7% Frw, and 10x 17mana/5frw SC's.

70% + 50% + 40%(boot) - 5% = 155%
Effective Frw = 67.6% frw, with 10 more skill points on BS, PN, and BA.

Keep in mind tho, Shaft, SS, Shako = slower cast rate.
Aim for 75% fcr
(50% from Wiz, 20% from Gloves, at least 5% from belt or 10-20% from Ammy.)

125% if you are doing NvN, or vs Sorc etc.
Cannot be achieved with Max DR.

I'll go on to No DR necro in the next post.
