The rest demand more dedication, involving repeated arcade battles to gather the hefty BP sums required. Patience is key here; grinding arcade mode often is unavoidable to round out your roster.
- Stages in Ys vs Trails also follow a BP unlock system. While some are available through the shop, others require grinding BP to access. The most challenging stages demand a hefty BP total or specific accomplishments to unlock, adding layers of replay value through both BP farming and mode completion.

Support Character Unlock Requirements
Support characters start limited, with only one available initially. Unlocking the rest is the heaviest grind in the game, requiring repeated clears of story and arcade modes with different characters. The game won’t let you simply replay arcade mode multiple times with the same character to unlock all supports; it insists on clearing arcade mode with every character in your roster.
When starting the game you will have access to only a single support character. Getting all of the others is the largest grind in the game as you’ll need to beat story mode and arcade mode multiple times. You won’t be able to repeatedly do it as the same character either, to get all support characters you must beat arcade mode as EVERY character.
