What level for Cloister of Ordeals?

[Tabris]

I got my airship now and would like to upgrade my classes. I am at level 17-18 now (Warrior, Red Mage, White Mage, Monk, Origins version) and can't say I got the biggest chance to even reach the castle.

Right now I'm levelling outside Gaia. What level should I be in before I started wandering towards the castle?

To be honest you could probably go there right now. Just make sure you have plenty of potions and the latest curing spells for your White/Red Mage. If you find you can't make it after a couple of attempts then level-up a bit more.

I levelled until they were all level 19, but I think I might level some more. Thanks, though.
