Assassin · physical (AD) damage
Briar is a Assassin that deals physical (AD) damage and brings airborne, stun, taunt, fear, slow. Some of their lockdown (airborne) ignores tenacity, so you dodge it; you can't cleanse or Merc' through it. Below is Briar's highest-win-rate build from high-elo games; open the counter-build tool to tune it against your specific enemy team.

Briar's attacks and abilities apply a stacking bleed that heals her for a portion of the damage it deals. Perpetually hungry, she gains increased healing based on her missing Health, but lacks innate Health Regeneration.

Briar leaps to a unit and hits enemies with The Heel Wheel (of Pain), stunning them and breaking their Armor.

Briar leaps forward and shatters her pillory, entering a Blood Frenzy that causes her to relentlessly pursue the nearest enemy (prioritizing champions). While frenzied, she gains increased Attack Speed and Move Speed, and her attacks deal damage in an area around her target. Briar can reactivate this ability while frenzied to take a CHOMP out of her target on her next attack, dealing additional damage based on their missing Health, and healing Briar based on the damage she deals.

Briar refocuses her mind, removing Blood Frenzy and channeling energy into a powerful scream that damages and slows enemies. While charging, she takes reduced damage and heals for a portion of her max Health. A fully charged scream knocks foes back, dealing additional damage and stunning those who collide with a wall.

Briar kicks her pillory's hemolith gemstone, marking the first champion it hits as her prey. She then beelines straight to them, fearing other surrounding enemies upon arriving at her target, and enters a state of complete hemomania. She will pursue her prey until death, gaining the benefits of Blood Frenzy as well as additional Armor, Magic Resistance, Life Steal, and Move Speed.
