I guess its a bug.. but one I like
Anyone else has tis effect?
Yes it's a bug, every time you quickload(I assume normal load too) when you're in a battle the buff is reapplied.
Actually, you're quite right. I played through that bit again due to an actual bug and realised when I reloaded my game that there was another blood rose right in front of me. Best place to hide it, I suppose. By which I mean growing in one of the mounds of festering bodies, exactly where everyone else would've expected to find it.
And as it transpired, I'd actually failed to collect the rose from the insane torture guy's lair. So there's all three of them.
Hey, there you go. It happens to the best of us.
