My party Options

[Shadan]

While I just finish BG1 soon, so I am planning my IA party. Since I am new in IA I would like any comments about my planned party:
gnome fighter/illusionist PC
Keldorn
Valygar
Anomen
Cernd (auramaster)
Nalia

I considered to get Haer'Dalis also, but he is similar to my PC (caster tank/damage dealer), so I skipped him. Also I am unsure about Nalia, but I think I need a thif at least for traps and locks. And I also need a high lvl arcane caster.

Hi!

My party is

Half-elven Fighter/Mage/Cleric with flail and hammer
Haer'Dalis with short sword later hammer or scimitar or axe
Keldorn with long sword + shield later dual long sword or longsword+bastard sword
Anomen with mace?
Jaheira with club and sling but i dont know what give her in later game, (any advise)
and Nalia

My general tactics is to send to the front my two tank: <CHARNAME> + Haer'Dalis
with mirror image and stoneskin and Haer's skulltrap sometimes useful Keldorn with his dispel and true sight is my debuffer in danger(sucks if dispel my protections but sometimes necessery) and my fighter (another question: Can he use the Thruth or the Judgement Day?)
Anomen and Jaheira my healers and buffers and Anomen is a brilliant fighter with Righteous Magic and another buffs, Jaheira is my third tank to swith in danger and my cannon fodder summoner Nalia not as stupid thief then the people said it. If necesserry she knock the doors and the locks and the mirror images, good saves of keldorn or the elemental/magic resistants protect me from violent traps.

I killed two group bandits, the Beastmaster, the Slavers and Tor'Gal, I skip Theshal because his Bone Fiends catch me in twelve different tries, I have the cleric-(the beholders so easy) and the fighter stronghold (the new Yuan-ti mages so scary and Torgal with his brilliant gem golem is cool, i shake when he summon a horde of mountain bears, and his regeneration rating is also cruel).

Have you got any advise where have i chance with a 9-12. level party without 6. level spells(improved haste )?

Sikret thank you! Your mod is very difficult and very challenging.
(For my first anvil game i use normal difficulty and Victor's Djinni merchant not for the items only the shop but they are so seducing)

P.S.: sorry my grammatical faults but my native language is hungarian and i am tired after work.
