I’m @ 13 kills on all PH’s and nothing ..fyi that staying on for 13 rounds not logging off .. killing sleeper for fun passing time …FIVE sleeper’s so far ! .. one back to back .. still no returned !!! … Just want to finish my hunter ?.. clearly something broken on the coding .. sounds like I’m not the only one .. I figured hey 100% bonus I’m good - nope ??
Its a little late to add this, but the mobs are not super resistant, they just have old world dragon rules. You must be under them/in melee range to cast a spell on them. Otherwise they resist everything
I've gone through as many as 150 Ph's for a named. However over time when I was farming him, I'd put the average at around 15 PH's per named spawn. Rate was pretty unstable.
