Rapid firing plasma gun. I have it set with a sniper barrel and it shoots almost as fast as an automatic but with twice the damage.

Has to be a tommy gun called Spray n' Pray, thing is so powerful(especially once I buff its two mod slots) that I can pretty much empty a clip and take down a behemoth before it even reaches me. The toughest legendary ghouls and mirelurks, chops their legs out from under them/tears their shells off leaving them powerless. Funny thing is, I left it sitting in my inventory forever figuring, eh it's just another tommy gun, now I don't use anything else. Only thing is that I have to watch no bystanders are around when firing at enemies, as it does splash fire damage as well

My favorite leagendary weapon I have found so far is my knee capping lazer rifle, which makes most boss and deathclaws enconters super easy.

Got a lucky musket critical shots do double damage. Is there a way to get the object id for this weapon? Really like the muskets in game the animations are real good and they look great. Would really like to use it in future playthroughs.

I was at the blood clinic last night and Dogmeat went off and killed a legendary rad-roach for me. Good boy. Got a Lucky 10mm with an advanced receiver. I think it does 27 or 28 damage. Two seconds later I found a non-legendary 10mm with an armor-piercing automatic receiver, but it does 14 damage.

So is it better to swap the receivers and go full auto with the Lucky blessing? Or is it better to keep the Advanced Receiver on Lucky 10mm and go with the high base damage?

Hmm, best finds are my bloodied super sledge ( damage increases as health decreases), got a plasma infused 10mm pistol ( +10 energy damage), a two shot laser rifle ( shoots extra round per shot for twice the damage and recoil), and a poisoned combat knife ( +10 poison damage).

I got a synth right arm piece that increases damage against humans by 15%. Can't quite remember it's name, since I never use it.

My best is probably the Fat Man I picked up last night, I can't even remember its effect (I don't use big guns).

But my favourite is the 10mm cryo pistol I picked up at level 7, still use it 20 levels later. +10 Cryo damage, I have it fully modded out and have invested in the pistols perk. Though hopefully I'll find a better pistol soon.

I got a Frenzied sniper rifle. Has a chance to frenzy target on each hit. I have yet to see the effect on a target, but I've found myself in several unreachable sniper positions where it could've worked out great.

I love some of the elevated roads where you are about 5 stories over the highest buildings and you pass over several raider, mutant camps.

+50 radiation 10mm handgun, I named it "goul maker" at the work bench.

I've found a bunch of legendary items but nothing that great. My favorite is a double barrel that shoots and reloads faster.

Have you seen the http://fallout4.wiki.fextralife.com/Furious+Power+Fist?

I found a .50 Sniper Rifle which ignores 50% of Armor, that's probably the best so far. Also I found a switchblade which does double limb damage.. that one is fun against ghouls lol

.308 rifle that does 25% extra damage at all times. I turned it into a silenced sniper rifle with the tracking scope and all the best mods, it has a damage rating of 89 and on top of that i have critical banker and stealth attack boosts. I got this gun around level ten, just hit level 27 now and i came within a sliver from one shotting a legendary alpha deathclaw! I love these legendary items, i didn't know they were in the game until i got it. I have a ghoul slayer rolling pin too haha. Plus some wicked legendary armor

Plasma Pipe Gun (+10 Energy Damage and chance to gooify enemies). I was wondering what I was going to do with all of my excess .38 ammo, but after I found this lil' beauty, I have no more worries. Was able to take out Swan at Swan Lake with this thing. Took a lot of bullets, but it was fun doing it. I rock this thing 80% of the time as it really helps to stockpile ammo for some of the hard-to-find calibers.

Plus, all of the nuclear material I find on slain enemies is pretty awesome too.

Lucky Gauss Rifle found it fully upgraded, 15% faster Crit replenish additionally Crits do 50% more DMG which means around 1000 DMG per crit. Found it with 16 Luck in SPECIAL; 10 with perks + 6 with gear. Now im building my char around Critical damage and AP.

Assault Rifle with 25 bleeding damage.
Laser Rifle which shots two shots instead of one, made it fully automatic and it is overkill.
Plasma Rifle with unlimited ammo capacity.
Old Faithful converted into a sniper rifle.
T-60 Helmet with faster AP regen.

An Assault Rifle that does 50% more damage against Ghouls, completely OP too. I don't think I've ever had a problem with Ghouls again after getting this weapon.

I heard a big explosion outside my settlement at Hangman's Alley and went out to check what happened, there was a dead mutant suicider on the ground and further away a dead mutant skirmisher and a dead legendary mutant who had dropped an instigating Fat Man (double damage to enemies with full health)...those are not "mini" nukes anymore...

Furious Power fist. Does more damage per hit with each cosecutive hit on the same target.

Popped some PSYCHOJET and bludgeoned some high level rad scorpion to death. Initial damage was 45 per hit, checked after he was dead, pip boy said damage was 145 or something like that.

Unfortunately I am not a melee character.

Otherwise, two different 10mm, one with +%50 limb damage. I use that one still, modded all the way up with silencer and recon scope. Other 10mm had a chance to stagger. Meh.

Also a steel pipe melee weapon with very low AP cost or regen, don't remember. Sold it.

Edit: double post

Poisonous Gatling Laser... Sadly, I play a Gunslinger, so it was useless for me.

I got a Wounding Napalmer from one of the last Ghouls in the Med-Tek facility. Fire Damage + Bleeding damage, it's like a weapon forged in hell

A glowing combat knife :/ Haven't even used it yet. - not the best I know.
I'd probably go with one of the laser rifles, or something with apparel. I managed to get a shotgun off a glowing radroach which was a bit weird, but ok.

Instigating Pipe Revolver Pistol. It does double damage to any enemy at full health.

Combined with the relevant perks (Better Criticals, Mister Sandman and Ninja), it's a hilariously OP sniper pistol that one shotted Swan with a body shot.
Granted, the Psycho helped.

Exterminator's Fat Man

Bonus damage against insects and Mirelurks. Good-bye, Radscorpions and blood bugs!
