Having just gotten

I wanted to test out its incredible limb damage bonus. I want to know what the best place to cripple an enemy is, and exactly what you can cripple. I did a bit of testing and found for deathclaws and ghouls, its best if you just choose a leg and shoot it. However, for more stationary enemies, I want to know what is best to cripple. Ive tried shooting the weapon out of a super mutant warlord's hand, but ended up just dropped the hp bar of both of his arms to zero with no result. Also, can you cripple the head or torso of an enemy?

tl;dr

can you cripple arms/torso/head of different enemies and what effect does it have on them

As I understanding crippling arms reduces melee dmg/ ranged accuracy, head also reduce accuracy.

Torso don't have a effect but like other crippled limbs the enemy takes extra dmg if you attack a crippled limb.

head, lower perception and accuracy- probably doesn't mean much for npc's but at distance you notice they aren't very accurate anyway so they can be less so.

legs- movement speed, some can be blown clean off and ghouls or robots will keep coming.

arms- aside from a momentary lowering of the weapon not sure? head used to be accuracy. You used to be able to shoot the gun itself. Now handguns has a disarm bonus, so i'd think crippling an arm will cause a drop but often they can pick it right back up but that takes time.

Best is to shoot them in the head and kill them asap.

Can shoot a radscorpions stinger but doesn't seem the most helpful thing to do. May limit poison and they can only use the clamps.

Shooting a mirelurks shell is just bad.

No ants with antennae in this one.

Stingwings have blood sacs, not sure the effect as they're usually dead by the time it explodes.

Shooting fusion cores with penetrating ability ejects them.

Shooting combat inhibitors on robots frenzies them.

Sensors I assume blinds them/ lowers accuracy.

All body parts can be crippled, though I'm not sure if bonus limb damage applies to each part. Logically it would only apply to arms and legs. In general crippling legs has the most noticeable effect. Even ranged humans and mutants are greatly hampered by being essentially immobile. I'll only bother with arms when fighting robots and synths, to really cripple their damage output. Against humans/mutants it's supposed to apply an accuracy penalty, but it's not very noticeable. On animals I guess it would lower their damage, but you're better off crippling the legs and finishing it off by firing at their soft spots (head or belly usually). Crippled heads and torsos are barely noticeable either.

Repost from nearby:

I found a Kneecapper somewhere. It has a 20% chance to cripple an enemy. LOL. I gave it an Automatic 38 Receiver and it had a Recon Scope already, so I just hose em' down with the most common ammo in the game for a cripple. I pull it out for all the big fast stuff.

Heh a regular gauss rifle will cripple any limb it hits anyway.
