You probably will see a lot of different builds for Briar because a lot of items work on her, pretty much anything with health/AD/ability haste is fair game and even some items outside that criteria
But the most common and generally effective build is titanic hydra into black cleaver and then stuff like deaths dance/spirit visage/steraks/guardian angel, kinda depends on the game after your first 2 items
Sundered sky can also be good as a 2nd item if they enemy team isnt building much armor, and blade of the ruined king can be good against champs that build lots of health
But if you go the bruiser build titanic is your bread and butter, its so good for her in every way
