crafted caster rings

are crafted caster rings on the same Principle as amulets (-5 / +4 if you buy from gamble)? are they worth it to buy from gamble with a high char level?

been crafting some ammys with lvl 95 and highest i got was required lvl 89;
got a ring from gamble, crafted with amethysts

Amn and jewel and it required lvl 96 lol

I think you would be better off crafting blood rings. Even if you get one without FCR, you at least have a chance to get a ring with some value (leech, str, maybe resists, life, etc).

Anyway, if you're looking to isolate desired mods on gambled rings, then you want a character level closer to the highest affix level and add 5 to that number.

E.g Fortune = aLvl 42 (cLvl 47)

Vampire = aLvl 86 (cLvl 91)
etc.
