Bartering determines your haggling skills with traders.
Level 1: All traders will drop X% off their base price. You earn Y% more profit when you sell items.
Bartering is a civil ability in Divinity Orginal Sin 2. Bartering determines your haggling skills with traders.
"Bartering improves your haggling skills. With each point invested, traders' items become cheaper and your items become more expensive."
Traders will drop X% off their base price. Traders will buy items at ( 1 / (1-X) )% normal price from you.
For example, if you have a 50% (0.50) discount, then you can buy a 100g item from a vendor for 50g (half off). If you are selling a 100g item to them, they will buy it at ( 1 / (1-X) ) price, which would be ( 1 / 0.50 ), or 200% price, at 200 gold (double price). This is different from the normal convention that one would expect -- instead of (for example) 30% discount and 30% higher buying price, one would (in this situation) receive a 30% discount and a 42% higher buying price.
Price formulas and discounts are as follows:
NPC selling you an item = ( base price ) muliplied by ( 1 - x )
Example Discount Values at 0 attitude:
- Lvl 1 -- 3.7% decrease in gold spent
- Lvl 2 -- 7.4% decrease in gold spent
- Lvl 3 -- 11.1% decrease in gold spent
- Lvl 4 -- 14.8% decrease in gold spent
- Lvl 5 -- 18.5% decrease in gold spent
- Lvl 6 -- 22.2% decrease in gold spent
- Lvl 7 -- 25.9% decrease in gold spent
- Lvl 8 -- 29.6% decrease in gold spent
- Lvl 9 -- 33.3% decrease in gold spent
- Lvl 10 -- 37.0% decrease in gold spent
NPC buying item from you = ( base price ) divided by ( 1 - x )
Example Discount Values at 0 attitude:
- Lvl 1 -- 3.84% increase in gold received
- Lvl 2 -- 7.99% increase in gold received
- Lvl 3 -- 12.49% increase in gold received
- Lvl 4 -- 17.37% increase in gold received
- Lvl 5 -- 22.70% increase in gold received
- Lvl 6 -- 28.53% increase in gold received
- Lvl 7 -- 34.95% increase in gold received
- Lvl 8 -- 42.05% increase in gold received
- Lvl 9 -- 49.93% increase in gold received
- Lvl 10 -- 58.73% increase in gold received
- Bartering-based price adjustments stack additively with Attitude-based price adjustments. For example, 19% discount from 100 attitude + 11% discount from Lvl 3 Bartering results in a net 30% discount.
- Attitude-based price adjustments are roughly equivalent to 1 level in Bartering for each +20 attitude. As such, having 100 attitude is equivalent to 5 additional levels in Bartering.
- Adjusted price vs the default price is shown when hovering over items in the trade window. Your current discount% is shown when hovering over the "star" that shows the vendor's current attitude and discount toward you.
- Because gold buy/sell values are always whole numbers, extremely cheap items tend to benefit less. For example, an item with a base value of 1g will remain 1g despite a 30% discount.
- Remember that Bartering price bonus and Attitude price bonus are character-dependent. Be sure to do all of your buying/selling on your character with the highest bartering + highest attitude with that particular vendor.
Due to the nature of how the math works when both buying and selling items, each additional point in Bartering becomes more valuable than the previous point invested. This also applies to attitude.
Going from 0% discount to 1% discount (+1%) is effectively a 1% discount. ( 100%- 99% / 100% = 1%)
Going from 90% discount to 91% discount (+1%) is effectively a 10% discount. ( 100% - 9% / 10% = 10%)
- The maximum barter is 12. This is attainable with 5 Civil skill points in bartering, Human race (+1 innate bartering, can be acquired with Fane's mask > Human), +1 Trading perk "Trader's Secrets," and +5 from items (Amulet with +1, Belt with +1, Captain's Jaunty Hat unique for +2, and Justinia's Gloves unique for +1). Along with increasing the trader's attitude to 100, this allows for equal sales and purchase prices for items in Act 2 (2 of these bonuses can only be acquired in Act 2).
- Starting in the Nameless Isle (Act 3), all goods increase in base cost by 17%. In Arx, this is increased to a 30% increase in purchase cost. While these increases do not universally affect every character, they do affect every Trader in Act 3 and 4, so it is practically universal from a gameplay standpoint. As such, it is best to buy all skillbooks in Act 2 before leaving Reaper's Coast. Since this does not affect the price when you sell an item,, the selling of your own goods can be done at any time to receive the same gold.
