Every skill tree in Fallout 4 has 10 different perks that the player can unlock with perk points. Some of these perks are incredibly useful; however, some of these perks are silly and don't have any meaningful effects. There are even perks that can be obtained through companions.
The Charisma skill tree is full of useful perks that can aid the Sole Survivor while building settlements, adventuring with a companion, and fighting mutants deep within the Glowing Sea of the Commonwealth.
10 Party Boy/Party Girl - Charisma 7
Alcohol is an interesting type of item in Fallout 4 because it isn't particularly useful by itself; however, with the Party Boy/Girl perk, it becomes much more powerful. This perk doubles the effects of alcohol, increases the Luck stat, and it takes away all of the negative effects that alcoholic beverages grant when it is consumed.
Although alcohol still isn't better than most chems after taking the Party Boy/Girl perk, it's still a worthwhile perk to consider since alcohol is abundant throughout the Commonwealth.
9 Inspirational - Charisma 8
With the Inspirational perk, the Sole Survivor's companions are given many different bonuses, including increasing their potential carrying capacity and ability to deal damage. Some of the companions in Fallout 4 are fun to have around, however on the harder difficulties, they aren't very helpful, which makes the Inspirational perk useful while playing on survival difficulty.
The Inspirational perk also grants companions immunity to friendly fire, which can be helpful if the Sole Survivor uses a damage type that deals with explosives.
8 Local Leader - Charisma 6
The Local Leader perk has two ranks, and it is worth taking both of them for players that enjoy building settlements. With this perk, supply lines can be established between different settlements, and this gives the Sole Survivor access to all of their building materials so that they can build at any settlement. Having access to all supplies and materials will not only be useful while building in a settlement but also while crafting weapon and armor upgrades at workbenches.
With the second stage of the Local Leader perk, stores and workstations can be built in every settlement. The stores generate caps, so it is worth building as many as possible to maximize the rewards.
7 Lady Killer and Black Widow - Charisma 2
The effects of these two perks change depending on what gender the character is playing as; these perks grant extra damage towards the opposite gender and make the opposite gender easier to persuade during dialogue sequences.
The Lady Killer and Black Widow perks can be useful for players who want to deal more damage toward human enemies; however, it isn't a very worthwhile perk compared to many other effects in the Charisma skill tree.
6 Attack Dog - Charisma 4
The Attack Dog perk is only useful if the Sole Survivor keeps Dogmeat in their party all the time, as it only affects this canine companion.
The Attack Dog perk gives Dogmeat a new ability that makes him bite human enemies, which will hold them in place and deal bleed damage. There are many better perks in the Charisma section; however, Attack Dog is useful for dog lovers.
5 Animal Friend - Charisma 5
The Animal Friend perk is unique because its effect grants the possibility to tame any animal in the wild, making them a temporary companion that will fight for the Sole Survivor.
There are many different types of animals in the Commonwealth, and animals such as Radstags make excellent battling companions when going up against all of the mutants that the Wasteland has to offer. The Animal Friend perk can be taken at Charisma level 5, which makes it easier to unlock than many other powerful Charisma perks.
4 Cap Collector - Charisma 1
Every Wastelander can benefit from taking the Cap Collector perk because its effect grants better prices at vendors, and taking the final stage of this perk even allows the Sole Survivor to invest 500 gold into a business, permanently increasing that vendor's buying capacity.
Although the Cap Collector perk may not be the most important perk to obtain right after leaving the Vault 111 location, it's still an incredibly useful perk that should be unlocked as soon as possible since it saves a lot of caps in the long run.
3 Wasteland Whisperer - Charisma 9
Wasteland Whisperer is similar to the Animal Friend perk; however, instead of taming animals that are found in the Commonwealth, it grants the ability to tame mutants. Mutants include creatures such as Deathclaws and Radscorpions.
The Wasteland Whisperer perk is especially useful during combat in the Far Harbor DLC since there are many different mutants that can be found in the swamps on the Island. Not only is Wasteland Whisperer powerful, but it's also a lot of fun as well.
2 Lone Wanderer - Charisma 3
The Lone Wanderer perk is one of the best perks that can be unlocked in Fallout 4 if the Sole Survivor doesn't have a companion by their side. If no companion is accompanying the Sole Survivor, then they will gain a damage boost, a damage resistance effect, and increased carrying capacity by up to 100 pounds.
The Sole Survivor can gain +25 action points if they unlock the fourth tier of this perk. The Lone Wanderer perk is even useful for players that have a companion by their side occasionally, but not all the time, since those players will also sometimes gain these effects.
1 Intimidation - Charisma 10
Although the Animal Friend and Wasteland Whisperer perks are powerful, Intimidation is arguably the best of these three perks since it grants the ability to intimidate any human, which can be useful during certain quests.
Humans can be calmed down by pointing a weapon at them and pressing a button, which then makes them passive towards the Sole Survivor. Players that enjoy being pacifists should consider the Intimidation perk since its ability is one of the only peaceful ways to settle a dispute between the Sole Survivor and another human.
