Stay in front of him just under his feet, all aoe will miss except the huge one. Pot after this one, you should be good.
So here is a real explanation, i tried to find it in the topic but everyone is just being a jerk at it.
Bramble have a bunch of easily avoidable attacks, just wait until he stop moving and hit him, keep your potion up all the time so you can ignore the red mist areas.
He have a āSpecial attackā that is the big circle aoe in front of him, looks like he is smashing the ground, this attack is super easy to avoid, but the main issue is everytime he does that he gain 1 stack of a buff that you can see sometimes on his target frame. At 3 stacks he will eventually use the big room aoe that does a lot of damage and is not possible to dodge (altho protective zone can mitigate all damage), Everytime you kill one of the summoning poles the buff will decrease 1 stack.
Strategy for not spending 1 hour doing it as a archer, kite him around the poles and dps both of them at the same time if you can, if this isnāt doable with your build just focus on the poles, as long as he never reaches 3 stacks this fight should be fairly easy. If you lack the dps to kill totems in time ( happened to me on a support character) Just ask around, there isnāt much you can do at this point iām afraid.
Good luck.

2 way to beat this fight solo
1.Doing mechanic
*Need some SP pot
Stand extremely near the boss. all Bramble auto-attack and most of itās skill does not hit there.
make boss face downward if you see heās use a Big punch in front of him with an AOE circle. itās mean heās summon a thorn to cast an entire undodgeable AOE damage. destroy it quickly with Kneeling shot or 2 full burst Multishot.
If youāre fast , High burst dmg and being lucky. Bramble will not use any area-wide AOE at all and finish the fight unscratched.
2.Burst it down
just stand under the boss and burst it down. youāll get 1 or 2 undodgeable area-wide AOE but with at least 2000 health and a bit of health potion youāll survive and beat the boss faster than 1st method.
Alternatively, get highlander/barbarian in your team.
