Tips:
You can only bring three characters here and Colet is already a fixed
member. So, I suggest bringing in Jeanne and Gilles. The target of
interest here is the Wyvern Lord that has the skill Mobility +1.
Although its rarity is just 3, that doesn’t mean that this skillstone
is common. Increasing your mobility increases your maximum movement
space so this will be helpful for low MOV characters like your tanks
and archers.
You will need to reach the Qrow Leader by setting up ladders (which
takes 1 turn). Sure you can bring archers instead but remember that
the Qrows have no elevation restriction; thus they can pretty go
wherever they want with ease.
