Financial values of items. How trading works and how likeability affects trading.

Guide to Values of Items and How Trading Works

All credit goes to Red riding hood the third!

Trading in General

  • Exchanging items with other survivors from other factions can only be done with gold.
  • Every survivor has between 0-50 gold available from the start.
  • If either of the parties dont have enough inventory space they wont be able to trade heavy items.
  • Neither will they be able to trade without sufficient gold.
  • The purchase and sell values of items depend on the likeability to your trader.
  • I will only take the financial values on neutral likeability. For the different factors i’ll add +% -%.

Likeability Factors

  • There exist 2 values for likeability. Both of them run in parralel to each other and have diverse effects.
  • The neutral middle point will be the standart.
  • The Two Factors are as followed: Like and Respect which can go into the negative.
  • Like: Hate – Like
  • Respect: Contempt – Respect

Likeability directly affects trading. It can positively and negatively change the purchase and sell value.

Purchasing information

[Positive scale (Discount)]

  • Like 100 Respect 100 (Admire) = -33%
  • Like 100 Respect 0 (Like) = -33%
  • Like 0 Respect 100 (Respect) = -33%
  • Like 100 Contempt 100 (Pity) = -0%

[Negative scale (Price increase)]

  • Hate 100 Contempt 100 (Despise) = +33%
  • Hate 100 Contempt 0 (Hate) = +33%
  • Hate 0 Contempt 100 (Contempt) = +33%
  • Hate 100 Respect 100 (Fear) = +0%

  • Each point of like and respect adds a 0.33% discount up to a max of 33% discount.
  • In retrospect each hate or contempt adds a 0.33% price increase up to a max of 33%.
  • By subtracting each negative and adding each positive points you get your final price in trading.

Selling information

[Positive scale (Better sell value)]

  • Like 100 Respect 100 (Admire) = +100%
  • Like 100 Respect 0 (Like) = +100%
  • Like 0 Respect 100 (Respect) = +100%
  • Like 100 Contempt 100 (Pity) = +0%

[Negative scale (Lower sell value)]

  • Hate 100 Contempt 100 (Despise) = -100%
  • Hate 100 Contempt 0 (Hate) = -100%
  • Hate 0 Contempt 100 (Contempt) = -100%
  • Hate 100 Respect 100 (Fear) = -0%

  • Items can be sold at 1/3 of their original price to merchants.
  • Each point of like and respect adds 1% to sell value up to a max of 100%.
  • In retrospect each hate or contempt puts a -1% to sell value to a max -100%. (Gives an error)
  • The sell value of an item at 100 like is the same as the purchase price of the item at 100 like.

Trading

Trading is a good way to get rare items without risking looting runs.

All items found in trading can be looted from the trader and vice versa looted by the trader.

All factions have a designated Merchant. Merchants carry large amount of money usually above 30 Gold.

Merchants also carry a wider selection of items. Like antigens and books.

Travelling merchants have a chance to have the white strain. If left alone they can infect your camp.

To avoid infection its best to isolate your survivors from making contact with other factions and let your leader deal with them until they leave.

How to Raise Affinity with Merchants

  • Complete quests.
  • Defeat survivors in fist fights.
  • Defeat Raiders.
  • Defeat Zombies.
  • Trade items.
  • Gift presents.
  • Heal survivors from other factions with a bandage.
  • Offer food to a hungry survivor for free.
  • Offer a drink to a thirsty survivor for free.
  • Talk with survivors occasionally.
