Merchants
Merchants are events that allow the player to use gold to buy cards from every king. There are three merchants, and each merchant appears once during a run. After the year's battle has concluded and the player has selected a card from the defeated king, the merchant offers 6 randomly selected cards for the player to purchase. The player can also spend money to reroll the merchant's selection of cards.
The first card a player buys costs 30 gold, and every subsequent purchase from the merchant costs 15 gold more. The initial reroll cost is 10 gold, and each subsequent reroll costs 10 gold more. Purchase costs reset to 30 with each new merchant visit but the reroll cost does not reset.
Types
There are three merchants, the Architect, the Sage, and the Warmonger. The three merchants appear on year 11, year 25, and year 31 of the run. If the king continues the run after winning the final battle, a merchant appears on year 40 and every 11 years subsequently. The order in which the merchants visit is random, but each merchant will visit only once in a run. If the run continues after victory, the merchants visit in a random order and merchants may make consecutive visits.
Each merchant has a unique inventory and sells cards from every king.
- Architect: sells all kingdom, building, and tower cards
- Sage: sells all spell cards
- Warmonger: sells all troop cards
In addition to their standard inventory, all merchants also have a chance to sell special cards.
