Yes, you can only have one bloodstain at a time. If you die, all the souls you had on your bloodstain are gone.
Oh man did I learn that the Demon's Souls way.....I didn't lose any souls up until I tried to get to tower knight....the way there,
"Oh hey there's a bridge with loot on it, don't mind if I do....what the fuck is that soun- YOU ARE DEAD." Dragon killed me.
"Okay so, maybe I should sprint there and come back real quick here I g- YOU ARE DEAD." Dragon killed me again.
"Okay, fuck the loot, let's just run across, let's hope I'm fast enou-" YOU ARE DEAD.
"OKAY FUCK, UNEQUIP EVERYTHING, RUN! YES MADE IT PAST! Okay so he holy attacked in the first part of the bridge so I should be goo-" YOU ARE DEAD.
"GOD FUCKING DAMN IT! Oh hey, an underground path, let's go there. Pretty dark, hope no one ambushe-" YOU ARE DEAD
"FUCK THIS GAME! NO, I MUST MAKE IT TO THE END! Okay, he's dead, he's dead, these guys are chumps, nothing will get in my way no-" YOU ARE DEAD. Killed by 6 random dogs in the tunnel
"fuck...this...shit....." Closes game till next day
"Okay, this is easily yadda yadda. Okay, seems I gotta go back up to the surface to cross the end of the bridge. I know the dragon will attack me, so let's see where the max point is that I can reach before getting burned. Got it. YES I RAN PAST! FUCK THERE ARE ARCHERS I CAN'T ATTACK! WHAT THE FUCK THERE'S A BLUE EYED KNIG-" YOU ARE DEAD
Repeat last scenario about 100 times. Losing souls each time and never gaining them back....
"FUCK YES, FINALLY, EAT MY SOUL ARROWS BITCHES! Okay...boss fight next...let's rape this HOLY FUCK THE FUCK IS THA-" YOU ARE DEAD
Oh....Demon's Souls....the only relationship where I will keep coming back despite the abuse I take...
