Yes, I do plan on going the Hunter's Eye route and doing some damage through sneak attack, so I'll take few feats just in order to not be retarded when using the crossbow. We have a cleric and our wizard plans on going the True Necromancer way (I heard it's bad, though), so I'm not too worried about undeads.

I also will probaly give up Evocation for DM pleasing, so I won't do the damage through spells. Not sure what to specialize in, though: Enchantment, Illusion, Divination (or maybe Conjuration for the Immediate Magic, though that runs a bit away from flavour and it might bother my DM a bit). The Familiar is also more of a flavour thing for him, so I'll get around without it. I might just pick divination to fit better into the character, though.

I was thinking of Extend/Persistent Spell for the Hunter's Eye and other shenanigans, is that feasible (I'm not getting a 5th wizard level) or not worth it, better to grab the few crossbow feats soon?

I have a +4 DEX modifier, so I maybe should just ignore armor altogether?

And, once again, you've been a huge help, thank you, everyone. :)
