It’s best to get these kind of perks bought early in the game to maximize the return, but is Chocobonus in particular worth the cost? 99 AP is a lot of points for only 10EXP each time
This one doesn’t have a direct return like any of the perks that give AP, bit it’s still worth it. 10 EXP is pretty low, but you get it every 0.35 miles. This makes it a lot less painful. If you get this at the start of the game you could net quite a bit of exp from using this one. It all comes down to how often you feel you will end up using a Chocobo. The more you use one, the more valuable this perk will be for you.
