From whom to buy a staff? (Diablo 2)

Good day. I decided to try to make Memory, for which I want to use a bolt like 3 energy shield, 3 chilling armor (or any other from the Frozen series) 3 enchant. Merck with insight, so it shouldn't merge too much in terms of mana. It is interesting to profit from the shield to reduce incoming damage and increase survivability if there is no cta or bo. Frozen Armor did not pump talents, it seems to be of little use to her, but still more defense is better than less. Well, an enchant for show - to give a measure to increase the attack rating. It seems that he should normally hit it anyway, on the folder that is a bonus.
Question: I saw on YouTube that Drognan bans with staves, on the norm he usually has enchant and low lvl skills, including 2 types of armor. But there are no staves with bonuses to energy shield. The level seems to be low. In other vendors, only blue (3 ... 5 acts). Nightmare and hell so all the more one blue. Persian lvl 90 Who tried to buy such a stick, does it make sense to swing a character to level 15-20 so that acts 3 and 5 also offer white clothes? Does this runword make any sense at all if I play for about forty? Which build is better for energy shield?
