If you could camp without a chance of having to wake up to monsters that are the same level as you... Maybe an upgrade for your tent that makes it so only low level monsters can wake you up... And to make up for the lost exp, make the quests in the game give you more experience.

I played through the whole game without getting interrupted while camping. Just camp for 3 to 4 hours at a time, wake up, and then camp again. You will never spawn any monsters that way.

Edit: This is for EB1. No idea if it's the same for the other 2.

Actually, I had no issues camping, its the speed that your PC slowly plods along the land that killed it for me.

If you couldn't guess from my Avatar, I'm more used to systems where a single click and hold can take you across screens.
