Lucky Vouchers are the many bonus items that you get your hands on by just logging in and playing Monster Hunter Wilds. Once active before a quest, a Lucky Voucher will let you double the rewards like monster parts and certificates that you will receive at the end of completing the quest.
However, Lucky Vouchers are not something that is readily obtained like the other crafting and melding resources in the RPG so it’s a resource that you might want to save for High Rank’s endgame loop.
The guide below goes over everything you need to know about using Lucky Vouchers in Monster Hunter Wilds.
How to obtain Lucky Vouchers in Monster Hunter Wilds

To obtain Lucky Vouchers in the game, all you will need to do is to log in to a server once every day. You will be guaranteed a Lucky Voucher as a part of your login reward, which you can then use in a quest.
You will be able to claim the log-in reward by starting Monster Hunter Wilds in Online Mode. When you are on the server, you will then need to tap the main menu button and then navigate to the Items and Equipment tab.
Here you will need to select the Login Bonus option which will then show you all the bonuses that are available and ready to be claimed.
Note: If you find the login bonus to be greyed out then you have already claimed the reward for that day. You will need to wait for a new day to claim your next Lucky Voucher.
What does a Lucky Voucher do in Monster Hunter Wilds?
Lucky Vouchers are a special item that you use at the start of a quest. When active they will then double the amount of monster materials that you will usually receive. hence, Lucky Vouchers are going to be one of the best ways of farming some of the harder late-game monsters that offer the highest rewards.
How to use a Lucky Voucher in Monster Hunter Wilds

There are three ways of using Lucky Vouchers in Monster Hunter Wilds:
1) Through Alma
The first and most straightforward way of using a Lucky Voucher is through Alma at the start of a quest. When you are talking to her to boot up a new quest, you will get the option to use a Lucky Voucher. This option is present on the left bottom-hand side of the window where you Accept and Depart on the mission.
2) From your inventory
The next option is from your inventory. If you have a Lucky Voucher and have started a hunt while you are in the middle of exploration, the game will automatically give you the option to use a Lucky Voucher. There will be a timer attached to it, and if it runs out you don’t use the voucher, but if you want to use it you will need to press and hold the Start button on Consoles and Y on Keyboard.
3) From the tent
You will also be able to activate any Lucky Vouchers that you have from the tent when accepting quests.
