Oldman, remember that the cleric classes have spells that prevent most of those conditions: Chaotic Commands is one spell I automatically cast on all party members after resting my party, and that spell lasts all "day". Remove Fear is another one - it removes fear from the party, but also prevents Fear (it's a blue heart). There is also a mage spell that prevents fear (blue heart in a blue circle). I cast it before every battle.

There is a mage spell - Remove Magic, I think it's called - that will remove most conditions from an affected party member. It looks like a white spiral. Also very useful for removing magic effects from an enemy.

Glad you're enjoying the game - I still do, too.
