The "Best" option is to reforge 5 pieces of garg stone armor with copper mallets for "of haste" to get them with 10 stam, then 1 garg earrings with copper runic hammer for 10stam.
Combine that with 15 ssi on jewels ( a ten and a five, or a ten and the town ssi bonus)
Reforge soulglaive for "of haste" to get 40ssi
Really need 50 ep to get your stats up
25 is ok, but mana will be low.
I made a pvm 210 stam setup using Soulglaive reforged for "of the vampire" with copper hammers to get overcapp mana leech (it only shows 50, but when you imbue ssi it Stays at 50 even with 30ssi) you can tell the overcap mana leech ones cause they usually have 2 mods only (mana leech and damage increase)
With this setup, i have 30ssi on weapon, 25 on suit (this is on a shard with no reliable ssi buff, so 2 10ssi jewels and ranger cloak)
Now that you can reforge earrings and amulet for 10stam, you dont need stam on jewels anymore, but it can still be usefull. not worth it imo, but you could use berserker breatplate and 2 5 stam jewels, or use one 4 or 5 stam jewels the be able to use 2 armor pieces with only 8 stam. This is really useful if you find a good 8stam garg shame loot arty, or if you want to reforge a piece for hci instead of stam
In my opinion 6 10 stam pieces, 15ssi on suit (or 10 with town bonus) unforgiven veil is best setup. Remember gargs get free 5hci, so only need 40 total hci on suit.
