To trade with ETA-0, you need Standard ETA Vouchers or Premium ETA Vouchers. One way to get them is by exchanging surplus weapon blueprints with the vendor. The developer warned because ETA-0 has limited stock, the number of blueprints you can exchange is also limited.<\/p>
For more dedicated players, there’s a way to grind ETA Vouchers. In the mid-season update, The First Descendant <\/em>introduces 400-percent difficulty for Infiltration Operations with more monsters and loot, including ETA Vouchers. These dungeons pose a significant challenge, as the final battle consists of not one but two bosses you have to fight at the same time.<\/p>
