The keys to any good tank build these days are the Greatshield Talisman, the Crab, and the Ironjar Aromatic.
All 3 require you to access the Altus Plateau. Which either requires you to speed run the scavenger hunt for both halves of the Dectus Medallion, or beat Magma Wyrm Makar.
The Dragoncrest Talismans are also good. The basic one is much easier if you to find Deathroot somehow, which can be gotten in a few ways, or you can just run to Dragonbarrow. The 2nd tier, requires you to get to the Altus Plateau. For most of the game the 2nd tier is good enough, generally.
The Pearldrake Talismans for non-physical damage can be gotten first through the 4 Belfries in Liurnia, or again, in Altus.
The Turtle Talisman is in the Weeping Peninsula.
So if you get the Dectus Medallions, you could theoretically get a tank build online without fighting any major bosses, but you'll have to beat Fort Faroth, which has end game level scaling.
