War gearing question.

You can buy i70 accessories - those can go a long way if you meld strength on them as they double up as DPS accs then.

Otherwise there's the darklight stuff at i70 that drops from harder dungeons. I wouldn't worry about farming those specifically. The drop tables are huge anyway.
Ultima hardmode drops i80 necks.
The extreme primals drop i90 accessories. Garuda ring, Titan ears, ifrit wrist.
The coil turns drop a full set you can see which turns give what here: https://docs.google.com/spreadsheets...#gid=182031962

What are the places i can run for rings and bracelets? still got i55's on me.

I'd suggest myth tomes (i90, cost 375 each) or i70 crafted. Myth tomes are probably the easiest to get. Coil or primals could get you roughly the same. i70 crafted is only good if you heavily (5x) meld it with materia. This costs a significant amount of gil, but the stats are arguably better than i90.

An i70 crafted when properly melded looks like: 10 Vit, 9 Str, and up to 12 of ~3 secondary stats.
An i90 looks like: 15 Vit, 16 Acc, 11 Parry.

Put another way: 2x i70 melded is more stats than i90 tank + i90 strength accessory. However, if you want pure Vit and neglect Str, then you don't mess with crafted.
