First of all, thanks for all the replies and suggestions!
Second... I know that this isn't "the perfect party". In fact, I clearly stated that I'm making an error taking both Aerie and Viconia in the first post.
(Anyway, thanks to all those agreeing with me on the matter!)
The three clerics are there for different purposes and roles, and no one of them will (ever) go away from the current party. Going to explain the reasons:
PC: Undestructable front-line juggernaut. (Ironskins+Draw upon holy might being the lowest level of buffing... ) Simply put, no one else can do it.
Plus, If I go away the game won't work I guess
Viconia: Priestishly things. Control undead. High-level clerical spells. Magic registance. The other two (PC, Aerie) have none of that. Plus, added Imoen-romance value.
Aerie: The awesome combo cheese that's available to no other than her
And again, addition to Imoen-romance interactions.
Now browsing all the posts...
@Silvanerian: thank you for reminding me where the Girdle of Fortitude is! Going to do the quest of the Unseeing Eye at once. Fine
@JackOfClubs: Give the Girdle to Mazzy? Get serious! She can boost her strenght to 18+ by herself wich would become 19 with the Improved Sword of Arworeen... It would make as much sense as to wear the girdle myself (str 18/00)
Sorry, I prefer to give stats-enhancing items to the characters that actually need them badly... (only mho anyway)
@User: I was partially aware of the fact that Viccy could have appreciated the Human Flesh Armor as a present...
But we're no evil party, so maybe poor Viccy's out of luck...
Still, I can't stand Adalon, I actually wish I could kill her more and more every time I meet her... she gets on my nerves... so maybe this time...
I will see how Viccy behaves with Immy... If she'll be nice to us, maybe she'l get "some" reward
@User again (more important): Fulcrum? Why not Pitchwife instead? I usually choose Pitchwife. Is Fulcrum good for some special trick? Tell me, tell me please... !
As a side note, no one is telling me of weapons to give to Aerie other than the Staff of the Magi! (Which I want to, and *WILL*, give to Immy instead!)
And which I suspect she would steal anyway if I don't...
