Please do not add another drop to icewall.
The loot tables are so crowded as it is.
I was thinking along the lines of AC augs but augs with only HP or only Mana at a decent level and maybe some hybrid AC/HP AC/MP HP/MP would be very nice as well.
Tier them so its not just an across the board junk item you can replace from seb.
Tier1: 10ac, 35HP 35MP, 5AC 20HP, 5AC 20MP
Tier2: 15ac, 45HP 45MP, 9AC 30HP, 9AC 30MP
Tier3: 22AC, 60HP 60MP, 15AC 40HP, 15AC 40MP
Tier4: 35AC, 75HP 75MP, 22AC 55HP, 22AC 55MP
Just a off hand suggestion with Tier1 droping in 35-55 level zones, Tier2 droping in pov,pos,chardok, Tier3 in ToV/St/Fire type areas and Tier4 in Fire boss events+
Craftable armor that is attunable would be sweet but I know how much work that would require to be balanced. With distillers being as they are I think these augs would not be to OP considering you can get better by raiding and it would give non-raiders -- Casual players a way to aquire decent augs while retaining LDON as top dog augs for the casual player. Seems like a win/win type of deal and would just require your desire to balance the stats as deemed appropriate, create a recipe series and populate the appropriate loot table.
Maybe trivial could be T1: 100, T2: 200, T3:300, T4: 350.
Would place a value on them, allow low end geared players to craft the easier ones and wouldnt hurt master skillers like me whom have the GM trophies.
