I just wonder why you invest points in Dual Wielding/Unarmed AND in Ranger Skills also ... while you said in your first post you playing a ranger ?
Maybe unlearn all skills at the Trainer platform and try another strategy ?
When the fight started I immediately jumped away form the Divine and run behind a pillar, use Hide in Shadows (HiS), look around for a enemy I can Charm or Blind ... but always first summon my Creature (a fighter with Rush Attack/Fatality is my best friend on the Finale Battle here).
I never was polymorphed by a magical spell in this finale battle, but I see your Intelligence is low (27) and mine was at least 80 so mine Indom. Will (to resist magical spells, see your Stats page for more info!)
was also high !
It's important you can run behind a pillar when using Hide in Shadows because most of the time if 1 or more enemies are shooting magic or arrows at you whilst using HiS it did not succeed !
While you're invisible you can always use the skill Healing without becoming visible !
My strategical steps :
1) Start a battle with Creature + Summon Ghost (and Demon if Ghost is in cooldown time).
2) Also very good to drink all highest possible potions (like Strength, Intell, Resistance, ..).
3) Jump back and use HiS, use Healing if needed
4) after that search for a enemy to Charm and/or Blind. If Needed take a Mana potion. At higher levels of Charm you can Charm more than 1 enemy at the time!
5) After that I mostly look if not to much enemies are try to kill my Ghost, so I use Stun Arrows + 'Rush Attack in' and if I've a equipment item with the skill Wirlwind on it I switch to that and use it to give my Ghost more place to breath and give it the chance to heal me (the Ghost can't defent himself and heal me at the same time!)
Or stun arrows + firewall is also a good weapon if you're surrounded !
Don't forget to take your time (pause the game to ponder over your next move !)
Good Luck !
