min. HP for Zrun?

2- What level do you think you could purchase it without having to use HP equip and survive the run? As a fighter, probably right away. As a sin, not until you're a hermit
If you used HP equips or pots? Probably right away. Maybe you'll have to wait a couple of levels as a sin.
What sort and how many of them (for the pots)? Grilled cheeses. Like 300 of them. The guild you're buying from will tell you.

Thanks all for your answers.
