@Notyloise the second Silverwind actually spawns right when you kill the first one IF you're quick enough. I soloed Silverwind X the first time without trouble, and when i came back for another round i thought it was a good idea to hunt safely and take my time. That was until i found myself surprise-pitted against 2 Silverwinds. I abandoned, for the sake of decency.

As for Hellblade, though the powder is a pain to get, the fact that the deviant is one of the easiest makes up for it, somehow. Or that's how it is in my book :° Maybe that's because Desire Sensor is being kind with me.
