To have an easier time progressing in Sword of Convallaria you will need to help your characters get stronger by increasing their level. While a gacha game to its core, the title does follow several tropes of the tactical RPG formula where getting more levels on your party members is a core part of gameplay.
However, as the game progresses, it will get significantly harder to gain levels on your characters consistently. So if you are looking to make progression easier in Sword of Convallaria, here is a guide that goes over some of the best ways to level up in the RPG.
Best ways to level up fast in Sword of Convallaria

1) Complete the main missions
The quests that are tied to the narrative are some of the best sources of Voyager EXP in the RPG. This is especially true for the early-to-mid game mark, so if you are just starting out in the narrative you will want to keep progressing in the Fool’s Journey story mode to have an easier time gaining levels.
2) Complete Crossing World stage missions
There might come a point in the main narrative when you are finding it hard to progress. IT can be because the enemy has more levels than you or you are not equipped with the proper combat stats.
When this happens, you should make your way to the Crossing World Stages and complete as much of it as you can. The stages tiger will offer you a chunk of Voyager EXP making it much easier to level up.
3) Complete your daily missions
Daily missions are a great source of rewards and Voyager EXP. These reset every day and you will be asked to complete a task that is not too tricky to accomplish.
Moreover, if you log into the game at two separate times, after 8 AM and 4 PM (regional time), you will gain Endurance Potions. This item will let you repeat more stages and gain even more EXP to help you level up fast in Sword of Convallaria.

4) Don’t sit on your Endurance Potions
As you burn through the various stages in the RPG, you are likely to exhaust your quota of Endurance Potions. Try not to sit on this resource after you acquire it from Daily Missions or through redeeming the Sword of Convallaria monthly codes.
Especially when you are completing the narrative, it’s best to use the position and repeat certain missions to boost your Voyager EXP gain.
5) Complete the Voyage Memento and Development quests
Completing the Voyage Memento and Development quests should be on your priority list as well. Once you clear all of them you will get your hands on some exclusive rewards including EXP that will make progression significantly easier.
6) Rank up your characters
Ranking your character will allow you to breeze through some of the hardest content that Sword of Convallaria has to offer. If you have not invested much resources in your party members you will struggle to progress and fail to get enough Voyager EXP to level up.

How does leveling work in Sword of Convallaria
Each of your character levels in Sword of Convallaria is tied to your account level which is also termed as Voyager level. So every time you are completing missions and gaining new Voyager levels, the level cap for each of your characters goes up as well.
Your characters will not be able to level up beyond their Voyager Level cap. So a good part of your playtime will go into completing quests that allow you to increase your Voyager Level as quickly as possible.
If your Voyager level is stuck, your progression will be stuck as well.
