U dont need 2 paladins- so dump keldorn...
Get Yoshimo, hes automatically replaced with Imoen in Spellhold... Due to cirsumstances which i wont reveal because they form a spoiler and i dont feel like putting a spoiler alert in this post wright now.
And yes, u already have a theif, but Nalia dueled from theif to mage at level 4...
This means her theif skills are not good at all.
