What kind of range do you need to solo bosses?

50k range is enough for HT. Your problem will be survival, not DPS. Leave the Cornians on the bottom alive, their bumps can protect you from 1/1 while seduced.

I don't know about PB.

And adding on to this, grabbing a familiar that heals a "large amount" of hp/mp also helps if you do get seduced.
