I'm hoping some body can answer this for me;

Are the spawnable tiers of staffmods determined by the items Base Quality Level or, by the Item Level of the drop it's self...?

I'm trying to figure out if its even possible to achieve a Metamorphosis w/ + (Lycanthropy, Werewolf, Poison Creeper... the Tier 1s).

If, staffmod options are determined by Ilvl of the actual drop... then 3soks = ilvl 33 (I think.. unless the req for native sockets differs from the req for the magic sockets mod) and T1 staffmods end at 24... Thus, impossible...

If however, staffmod options are determined strictly by the Qlvl, then the iLvl 60+ Spirit Mask (Qlvl 24) that drops in hell COULD still spawn T1 Staffmods AND achieve 3soks...

Hopefully that tracks and I'm using my terms correctly.. Thanks for any input.

Both 3os and staff mods are purely based on the item ilvl (not the qlvl) so tier 1 staff mods with 3os it's likely not compatible (I did not check the ilvl for 3os for druid helms but I take your word for it since you look like you have enough base knowledge to have checked them right)

The "trick" you are trying to use using a high qlvl base works to be able to get mods that ask for a high alvl (like +2druid) but that would only help for rare helms not for bases, sorry

Thank you for your response, it is as I feared. This does however explain why I never saw (and don't see) people trying to find claws with Claw Mastery for their Chaos / Mosiac set ups.... Which would seem to be an obvious choice, but by these same conditions, impossible. Learn something new every day

All the info you need is in my guide in my sig.

It's a bit long tho, so I can answer to your questions briefly...

Like it was mentioned, both staffmods and max number of sockets are based on ilvl

But here's more info :

Staffmods Tiers vs iLvl
01 ≤ iLvl ≤ 11: T1, T2 (base T1)
12 ≤ iLvl ≤ 18: T1, T2, T3 (base T2)
19 ≤ iLvl ≤ 24: T1, T2, T3, T4 (base T3)
25 ≤ iLvl ≤ 36: T2, T3, T4, T5 (base T4) (D2C: iLvl ≥ 25)
37 ≤ iLvl ≤ 99: T3, T4, T5, T6 (base T5) (D2X only)

Each base Tier is randomized by :
20% chance of +1
50% chance to stay unmodified
20% chance of -1
10% chance of -2

But no, the max number of sockets is not equivalent to the magic affix.
And this 3os magic affix is not even based on the ilvl in the first place... it's based on the alvl, which is a number that comes from the relation between the ilvl versus the qlvl of each item.
Not that it's relevent here, cuz again, I'm talking about the prefix 'artisan' for 3os.

For any white pelt, the maximum of 3os is unlocked at ilvl 26.

So no, you sadly can't achieve your goals since ilvl 26 sets the staffmods on a base of T4, and they can drop max 2 tiers.
