Borderlands question [Solved] GA inside

I remember about this when I was playing Borderlands 2, you have to get a different weapon that has ammo that penetrates shield, every type of ammo penetrates a type of defence

IMO i think you might just need to grind some enemies or do some side quests and get better loot if your getting one shot. If your level is way below the bosses or mobs level then your weapons do alot less damage.

Everything's about the drops in Borderlands, especially early on. You can roam around a bit, grab some better gear, gain a couple of levels and then circle back to the boss that's bugging you. It should be easy enough after a while.

Alternatively, you can co-op with a buddy, which gives the mobs another target and more than doubles your firepower. Especially if it's a higher level buddy that's boosting you.

1.use a shock element weapon cause it very effective against shield
2.use burning or flame weapon after the shield down cause it very effective against flesh
3.if it isnt enough go crazy with the grenade,launch them all
good element weapon was maliwan or just use

Whats the boss/quest name? Also Elemental weapons help a ton http://borderlands.wikia.com/wiki/Elemental_Damage

What level is the enemy? If he's higher than you, then you might want to grind some enemies and level up first. My playthrough was with a hunter too and I don't remember having a problem. What boss is he exactly?

Edit: I also played solo.

borderlands combat can be extremely easy or hard, depending how much difference there's between you and your enemies level.
if i remember correctly, ~5+ levels makes fights almost impossible as you deal no dmg and receive A LOT more.

Grind more, and you probably want to change your weapon. Sniper is not best weapon to solo boss

Whats the name of the boss? Also I think you are under leveled. I played Borderlands 1 and 2 all the way solo and I got stuck just a few times (most of them with raid bosses).

Grind for some weapons and check the shops in case they have something in the daily offer (I got 3 legendary weapons from shops).

Also kill other bosses you have killed before to grind some gear. Check what kind of elemental damage you have to use to kill the boss (most of the time you just need a shock weapon and a fire weapon but it varies)

Was it Bone Head? While he can be found easily right next to Fyrestone, it may be better to leave him alone until you get the specific mission (and have the necessary level by that time)
Side note: sniper rifles are great for any class when wandering around, but they are not so great for close-quarter boss battles, regardless of the class.

Guessing this was Bone Head? He is a PITA until you get equal/over level on him.

On the plus side he drops a nice SMG once you kill him

some bump

using sniper for a boss? man you should use a good rifle.
otherwise farm a little more and come back later

Bump! It's amazing that the problem was solved that fast!
