Gambling Mechanics

[whathuh]

Amulets are really only gambles at clvl 95+ since you need an alvl of 90 to get the +2 skills on them. Also, crafting is a much better way to get better amulets at that level, just make sure you use high ilvl stuff.
42: Prismatic
36/90: 1/2 Skills
20/40: 1/2 Skill tree
24/57/85: Leech/Locust/Lamprey
15/58/78: Bat/Wraith/Vampire

Rings also are better off crafting, but the good alvls are:
56: Rainbow
18: Any single resistance 21-30
14/47/77: Leech/Locust/Lamprey
25/58/86: Bat/Wraith/Vampire
74: Titan

Circlets are like amulets, only really good with +2 skills which require alvls of 90.
15/28/78: Bat/Wraith/Vampire
14/47/77: Leech/Locust/Lamprey
42: Prismatic
5: Deadly
36/90: 1/2 Skills
20/40: 1/2 Skill tree

Basically gamble with your highest level character, but dont bother to try and get +2 circlets/amulets if you aren't above level 90. Try using the affix calc at diabloii.nu if you want to figure out more
