The special exchange of "Arknights" is a prop exchange interface open to players. If you want to upgrade the attributes of your equipment, you can directly exchange it with game currency, but the quantity is also limited. Players must choose the appropriate props to upgrade here. Below I will introduce the strategy to you, I hope it will be helpful to you.
ad hoc clearinghouse
In the special exchange house, 4 high-level materials must be exchanged for a total of 1280 bounties;
Secondly, the ordinary limited edition materials. To be honest, the solid source rock group and the polyester group are not very cost-effective. They can be purchased in regular notebooks. The gel is quite good, but after all, it is limited and requires 775 bounty ( Only exchange for gel 250 bounty);
Then depending on the demand, you’ll need gantry coins, combat records and parts. A total of 620 bounties are needed.
Special reminder, the above exchange does not include unlimited exchange of materials, such as skill books, different irons, ketone agglomerates, devices, chips, etc. To be honest, they are better than exchanging stones. Isn’t 1-7 delicious?
