Chocobo Companion SP

[Naria]

That depends. If you max out a rank you get a special barding for your chocobo for that rank. Healing Choco's get whm barding, Tank Choco's get Heavy Armor barding, etc. The barding is only cosmetic though. Otherwise it is probably best to make a hybrid, depending on what job you play and what you need.

Edit:
You can also respec the Choco's SP later if you change your mind by purchasing a Regean Pepper with seals and feeding it to them. This requires access to a stable via housing and either a large amount of GC or Allied seals.
