I dont think you need to necessarily say 'hey start here' but if it were me I'd change the reward on the outskirts to earning your class as a more natural suggestion to go there first since it's a power up. And you need power to survive.
Also balance wise a couple initial notes off the top of my head :
Id change the white mage to be maybe +1 or +2 flat healing or give them a once per location self heal. a flat +d6 to healing each time you use a potion is pretty strong.
I also feel like the grey ooze ought to be maybe just a trap. As it stands your not likely to have destructible items at this point and you can just land there and effectively just roll gold since it does no damage. Unless you switch it to like 1 damage + ruins an equip or chance to ruin equip instead.
Then on the same location (outskirts) id change goblins to just bandits or thief.Just so you don't double dip names then just call it a trap since it auto triggers.
