A combination of appearance and charm. A high Charisma is important for characters that want to influence people with words.

— Fallout in-game description

Charisma is one of the seven primary statistics in the SPECIAL character system.

Fallout, Fallout 2 and Fallout TacticsEdit

In Fallout 2, Charisma also determines the number of base companion slots the player character is given. This number is equal to their Charisma score divided by two, rounded down. As an example, with a Charisma at five, two can be recruited. Please note that one companion can still be recruited (in a few cases) even with the lowest Charisma score.

Predesigned Primary Charisma-based Characters (PPCC) of Fallout are Albert, and in Fallout 2's case, Chitsa.

In Fallout Tactics, Charisma is, at best, a secondary trait. Due to the nature of the game (i.e. almost exclusively combat-based) it is feasible to complete the game easily with 1 or 2 Charisma with no penalty. The only role is that when the Warrior starts with Charisma of 10, their rank is Senior Initiate, rather than Initiate. It is involved with the Barter skill and promotions, and is required for the Leader and Divine Favor perks. A low Charisma, on the other hand, gives access to the Loner perk.

Ways to increase Charisma in FalloutEdit

  • Find the Singer random encounter. Speaking with Patrick the Celt and passing a Speech check will increase Charisma by one.
  • Pop some Mentats for a temporary +1 Charisma.

Ways to increase Charisma in Fallout 2Edit

  • Install the blue memory module into ACE, then request the following surgery. Charisma will be increased by one.
  • Take the Gain Charisma perk for another point.
  • Having the mirrored shades, obtained from Mason (Salvatore's Bar, must be looted) or one of the graves in Golgotha, active in one of the item slots increases Charisma by one point.
  • Pop some Mentats for a temporary +1 Charisma.

Fallout 3Edit

Modifies: Speech and Barter skills, NPC Disposition

Charisma increases the disposition of all NPCs, which makes Speech checks easier. Disposition is also affected somewhat by Karma (most NPCs like good characters more), quests (doing a quest in a way an NPC likes can dramatically boost disposition), and dialog options (being a jerk in conversations can lower disposition a little). Charisma also affects the Barter and Speech skills. Characters who use Speech will want at least a decent Charisma, but adding points to the skill is almost always better than adding points to the score. Characters who do not use the Speech skill have little use for this SPECIAL score.

There are also general Charisma checks in dialogue with some characters, in addition to Speech checks. Avoid wearing things like Enclave Power Helmets, as they deduct 1 point of Charisma while equipped.

Ways to increase CharismaEdit


Fallout: New VegasEdit

Charisma in New Vegas modifies Barter, Speech and Companion Nerve. Companion Nerve gives each companion in the party +5% to their damage and armor, up to a maximum of +50% at 10 Charisma.

Regardless of Barter or Speech level, some interactions will not be available with a too low Charisma (Ex. Corporal Betsy). These ultimately do not have any significant effect on game play, nor do they provide any special bonuses.

Ferocious Loyalty 6 6
Animal Friend 6 10 Survival 45

Ways to increase CharismaEdit



If the Courier's Charisma stat is the most extreme (highest or lowest), Doc Mitchell will either comment "them bullets didn't affect your charm none." (for highest) or about frontal lobe damage. (For lowest)

Fallout 4Edit

Charisma is your ability to charm and convince others. It affects your success to persuade others in dialogue and prices when you barter.[1]

Charisma affects the maximum amount of settlers allowed at a settlement:

Max Population = 10 + Charisma

It also affects item buy/sell values; the value of an item for buying or selling is its innate value multiplied by either the buying price modifier or the selling price modifier:

Buying Price Modifier = -0.15 \times Charisma + 3.50
Selling Price Modifier = 1 / Buying Price Modifier

In addition it affects your ability to charm and convince others: It affects your success to persuade in dialogues.

Charisma Buying Price Modifier Selling Price Modifier
1 3.35 0.2985
2 3.20 0.3125
3 3.05 0.3279
4 2.90 0.3448
5 2.75 0.3636
6 2.60 0.3846
7 2.45 0.4082
8 2.30 0.4348
9 2.15 0.4651
10 2.00 0.5000
11 1.85 0.5405
12 1.70 0.5882
13 1.55 0.6452
14 1.40 0.7143
15 1.25 0.8000
16+ 1.20 0.8000

Other price factors are below.

Modifier Buying Price Modifier Selling Price Modifier
Cap Collector 1 0.90 1.10
Cap Collector 2 0.80 1.20
Barter Bobblehead 0.95 1.05
# of Jerky Vendor issues = 0 1.00 1.00
# of Jerky Vendor issues = 1 0.97 1.00
# of Jerky Vendor issues = 2 0.94 1.00
# of Jerky Vendor issues = 3 0.91 1.00
# of Jerky Vendor issues = 4 0.88 1.00
# of Jerky Vendor issues = 5 0.85 1.00
# of Jerky Vendor issues = 6 0.82 1.00
# of Jerky Vendor issues = 7 0.79 1.00
# of Jerky Vendor issues = 8 0.76 1.00
Friend Discount - Connie Abernathy 0.75 1.25

Friend Discount is when you get better prices from a vendor for completing a quest. For example, returning the locket to Connie Abernathy's husband unlocks a Friend Discount with Connie. Other vendors may have the same or other discounts.

Multiply the modifier from charisma and all applicable modifiers above to get the (near) final modifier.
If you get a final buying modifier that is less than 1.2, the game will use 1.2.
If you get a final selling modifier that is greater than 0.8, the game will use 0.8.

Note: The minimum purchase price is 120% of the item's value, and the maximum selling price is 80% of the item's value. It appears like this applies even after you get a discount from a Vendor.

To get the best prices:
Without any of the other factors above, you need 16 CHA for buying, 15 CHA for selling.
With Cap Collector 1 Perk, you need 15 CHA for both buying and selling
With Cap Collector 2 Perk, you need 14 CHA for buying and 13 CHA for selling.
With Cap Collector 2 Perk, and the Barter Bobblehead, you need 12 CHA for selling.
With Cap Collector 2 Perk, the Barter Bobblehead, and all 8 Jerky Vendor issues, you need 10 CHA for buying.

To get maximum temporary charisma (for example to raise max population on settlement):
Equip Militia hat or any other hat raising charisma (+1)
Equip Black-rim glasses or Fashionable glasses (+1)
Equip Summer shorts (+2) or Green shirt and combat boots (+1) (Summer shorts fills chest armor slot, green shirt and combat boots do not.)
Equip as many "Sharp" type legendary armor pieces as you have (up to +5)
Drink Beer or any other alcohol except Bourbon, Rum, Vodka, Whiskey or Wine (+2, does not stack with other alcohol types, party girl tier 2 perk doubles the charisma gained by alcohol.)
Use Grape Mentats (+5)
Use Day Tripper (+3)
Use X-cell (+2)
