"Plz help someone(raze, if possible:) )"
<img src="/ubbthreads/images/graemlins/suspicion.gif" alt="" /> I would have thought you would want help from someone who had played a mage, but OK..... <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
Do you have Curse? A few casts of that before switching the Elemental Hail will make the attack much more effective. You can drink a shadow potion if Josephine casts Blind on you, to wait for it to wear off. Area effect spells that do not require a target (Hell Spikes, Elemental Hail...) may not turn you visible (don't know, never tried), but even if they do, they will work when you are blind. Blind / Hell Spikes works well against Josephine, if you get her first, or survive until her spell wears off.
If you have a spare skill point, level 1 of the survivor's Deadly Gift combined with a couple scorpion traps would make it an easy fight. You can run up the ladder after releasing them...
I take it not much of your equipment has a vitality bonus? Even as a warrior with only a single stat point put into intelligence, towards the end of the game I had over 500 magic points from equipment bonuses. Do you have lots of spare charm slots? A couple silver charms (bought from Kistandalius or Blake in Ars Magicana and Corinna or Mpenzak in Verdistis) would add 80 (IIRC) vitality each. You may want to just use pause and a lot of
restoration potions, since gold charms can be bought in the wastelands.
