'''Trading''' is a central gameplay mechanic in [[Baldur's Gate 3]] revolving around the sale and barter of [[Items]] and [[Gold]]. Depending on which [[Characters|Character]] is talking a given [[Trader]], including the trader's [[Attitude]] to the character, the character's [[Persuasion]] value, and the [[Difficulty]] setting of the game, a trade price multiplier is calculated. This multiplier is then applied to each item's inherent value, giving the prices for the character.
'''Trading''' is a central mechanic in Baldur's Gate 3. Depend on which character is talking a given trader, including the trader's attitude to the character, the character's [[Persuasion]] skill level, and the difficulty setting of the game, a trade price multiplier is calculated. This multiplier is than applied to each item's inherent value, giving the prices for the character.


The price modifier is calculated as:
The price modifier is calculated as:
Line 11: Line 11:
: <tt>P = max(1.0, 2.5 - persuasion modifier - difficulty modifier - attitude modifier)</tt>
: <tt>P = max(1.0, 2.5 - persuasion modifier - difficulty modifier - attitude modifier)</tt>


An item's value is multiplied by the price modifier when buying, and divided by the modifier when selling, i.e. the smaller the total price modifier the better for the player.
An item's value is multiplied by the price modifier when buying, and divided by the modifier when selling. Favorable modifiers are negative and unfavorable ones positive.

=== Persuasion modifier ===
=== Persuasion skill modifier ===
A character's [[Persuasion]] value affects prices. Positive values will make prices more favourable (higher when selling, lower when buying) and vice-versa. On [[Difficulty#Explorer|Explorer difficulty]], characters have a higher Persuasion value if they are proficient in Persuasion because the [[proficiency bonus]] is higher on that difficulty. Each Persuasion value point changes the total modifier by 0.1., as detailed below.
A character's [[Persuasion]] skill modifier affects prices. Positive modifiers will make prices more favorable (higher when selling, lower when buying) and vice-versa. Each Persuasion modifier point changes prices by 5%. In Explorer difficulty, characters receive an additional Persuasion modifier if they are proficient in Persuasion, as detailed below.


: <tt>Persuasion modifier = Persuasion value × 0.1</tt>
: <tt>Persuasion modifier = Persuasion skill modifier * 0.05</tt>

On [[Difficulty#Explorer|Explorer difficulty]], the difficulty modifier is 0.5.  
In Explorer difficulty, the difficulty modifier is 0.5, meaning all characters receive a 20% favorable bonus to prices. If a character is proficient in [[Persuasion]], they receive an additional Proficiency modifier depending on their level. This increases the persuasion modifier.
 
If a character is proficient in [[Persuasion]], they will benefit from the higher [[Proficiency]] bonus this difficulty provides, depending on their [[character level]], as detailed in the table below. This, in turn, increases the Persuasion modifier.

In Tactician difficulty, the difficulty modifier is &minus;0.5, meaning the total modifier is increased, making it more expensive to buy and lowering the sell price.
In Tactician difficult, the difficulty modifier is -0.5, meaning all characters receive a 20% price penalty.

A trader's [[Attitude]] score represents how friendly a trader NPC is with a certain character. Each point of Attitude changes the total modifier by 0.005, resulting in a maximum attitude modifier of 0.5 at 100 Attitude.  
A trader's [[Attitude]] score represents how friendly a trader NPC is with a certain character. Each point of Attitude modifiers prices by 0.25%. The maximum attitude modifier at 100 Attitude is 2.5, or a 25% price adjustment compared to 0 Attitude.  


: <tt>Attitude modifier = Attitude × 0.005</tt>
: <tt>Attitude modifier = Attitude * 0.0025</tt>
 
Attitude is visible in the Trading interface under the trader model. Hovering on the meter displays the exact Attitude score. Attitude is per-character, and can be modified by friendly or hostile actions against an NPC. One of easiest ways to gain Attitude is by gifting [[Gold]] or other items to a trader using the Barter interface. The amount of gold required to gain attitude scales depending on the level of the character.

==== When is it optimal to gift? ====
Assuming you are only looking to buy once from a trader, we can calculate the cutoff above which gifting saves more than the value gifted.
: <tt>price reduced per gift value = base value / level modifier × 0.005 > 1</tt>
If this value is above 1, every gold gifted is worth more in discounts, so you save by raising attitude to 100.
: <tt>base value > 200 × level modifier</tt>
For example, at level 4, this cutoff would be 200 × 8 = 1600. If you are buying more than 1600 total base value of items, you actually spend less total gold by gifting 800 gold to raise the trader's attitude to 100 first. Note that this refers to '''base value''' of items, not the price you see at 0 attitude, which is usually more than 2 times the base value (see price modifier at the top of the article).

The trade price modifier is set depending on the character that initiates the dialogue with a trader. Even if the active inventory is switched in the trader screen, the first character's trade price modifier remains in use. It is thus a good idea to initiate all trade dialogues with the character that has the best trade multiplier.
