Inn

Inns are special locations in Xenoblade Chronicles 2 and Torna ~ The Golden Country that allows the player to raise and lower their level, and when in areas affected by the tide of the Cloud Sea, inns can also be to change the height of the tide.

Levelling
Levelling up and down at an inn uses a system called Bonus EXP. Bonus EXP is not added onto a character automatically like normal experience, and the only way to level up with it is at an inn. Levelling down a character gives the character reserve bonus experience that matches the amount of experience that those levels would have had, otherwise, meaning levelling down can be reversed without penalty. This is useful to help match characters' levels to, for example, quests or unique monsters, and can also be used to quickly gain bonus experience to sell to Traveling Bards.

The ability to level down is gained in, and so players can only use an inn to level up with bonus experience initially.

Tides
In areas affected by tides, choosing to rest for a long time at an inn will change the tide, between high and low.
