There might be a misunderstanding between Blue and Benjamin regarding the level of the item. I hope this information and examples helps clarify things. This information does not extend to Crafting.

1) All items have two levels to consider: iLvl (item level, this is not observable, this determines mods that can spawn on the item), and rLvl (requirement level, this is the observed level required to use the item, it is generally the level of the highest mod or the base item itself, whichever is higher).
2) Mods have two levels as well, iLvl that they can appear on, and rLvl used to determine the char level needed to use that item. The mod for +3SkillTab has iLvl=60 and rLvl=45.
3) Circlets have an rLvl of 45 in HU, so they will never be lower than char level 45 to use. If the circlet spawned with a mod with rLvl 51, then the circlet would be level 51 to use.
4) The iLvl of a circlet depends on the monster that dropped it, or the character level that gambled or imbued it. Just like in Vanilla, the iLvl of Circlets gets a +3 bonus for the mods that can appear on it, gambling yields iLvl within -5 to +4 of the char level, and imbue gives the item a +4 iLvl bonus. For example, if you imbue a circlet at char level 53, then the circlet should be capable of mods that require an iLvl of 60 (e.g. +3SkillTab needs iLvl60).
5) Rolling a rare item using an Adamant Glyph does not change the iLvl. For example, if you wanted to roll a +3SkillTab Circlet, then gamble it with a char at level 62 (since the iLvl could be as low as 60 when gambling in this case), or imbue a plain circlet at level 53, and then roll that circlet using any character (since the rolling recipe does not consider char level).

If there are specific mods that you are after, look at MagicSuffix.txt and MagicPrefix.txt for the iLvl needed to spawn them.

Ok so i am probably terribly stupid after this explaination but i dont get one part here...

...why the heck would i need to have a char at lvl 62 .. 17 lvls higher in order to gamble for a lvl 45 circlet?

That makes no sense to me for some reason.. what am i missing...

ilvl=item lvl, the mod for +3 tab skill needs to be ilvl 60
rlvl=requirement lvl, this has nothing to do with what the ilvl is. it only affect at what lvl the char can wear it.
so to gamble at lvl 62, it will ensure you a ilvl 60 because gambling will use char lvl to determine ilvl.

Oh bummer i have a long ways to wait then

where can i find this?
is it same as on areat summit page?
if so,why cant i roll or find "+all resists "charms?
do they exist at all?

1) The text files are located in patch_d2.mpq. Files that end in MPQ are just compressed files, kind of like .zip or .rar, so you just need to find a suitable decompressor program.
2) No, the iLvl and rLvl of some mods and items have been changed in HU. There are also a few mods added (such as a higher tier of +EleDmg to attack charms).
3) ResAll charms exist, I've even found a couple this ladder already (although I sold the 3%ResAll GC). The Frequency value of "Shimmering" mod is relatively low, so these charms are rare. The iLvl is about 35 for any size of charm, so if you are farming for them in Hell, then you are reducing the odds of finding them by quite a bit; however the non-res mods available at higher levels are pretty nice.

Here's something u may like Ben: i got a +3 traps rare circ ft in hc, and you can use quads sockets in helms here, well maybe its a bit too expensive for you right now and thats why u wanted to use triples...

Well so if you still havent found your circ and can offer some gems or runes for one /m *dieu
