I like it tbh.
But you can make this bit a bit different
Make it only the party members can warp back. Because if they don't have a priest with them, they're completely fucked. Just make it only the party members can come back.
Let's say.. people sell sniper set for 25 and sniper bow for 60.
So that's 85
But if you buy from overpriced people then you might get it for 100+
LOL.
