You can buy the ferrystones for gold or loot them. They cost 10k gold. I had over 30k at level 10. Buying them is literally nothing mid to late game. You can also fast travel with carts that let you snooze or fight monsters. They are actually more interesting than ferry stones cause you get exp and loot.
Dude. I get that. If that was the case here I’d be up in arms too. But it’s not. Not even close. This is the equivalent of complaining that you didn’t get the “Twin Humanities” starting gift in dark souls. It honestly is inconsequential to the experience while playing the game. NOTHING is worth paying for and anyone saying that hasn’t played the long enough to realize that. The game is perfectly playable in every aspect and you miss out on nothing.
