... however there was some [not so nice word for a female warrior] who would kill me with a single twitch of her finger before i could take a single step; for her i had to lower the difficulty - i mean how do you kill fight someone who makes you fall dead before you take a single step ?
...
I think you mean "Geshniz" ? She use a strong "Magic Blast" (and Magic Blast go very Fast

)
I sommon Creature & Ghost and then go to speak with her and after that I run/jump away back and used Hide in Shadows (L2 or 3 I had and WARNING : look out no enemies can shoot or use a spell at you while using Hide in Shadows, or it will fail and you're still visible!),
run back to her servants (while I'm still INvisible!) and try to kill them first ... OR better!! >> Charm one of them so he start fighting his own female boss, Geshniz

(used Charm L5)
I this case the fight is way more easy!
