Thank you all for your help!

I'll start my playthrough this weekend. You sold me on a Half-Orc Eldritch Knight Wizard multiclass focusing on heavy armor and CC spells such as Thunderwave, Gust of wind etc. In theory, if I understand correctly, this would allow me to get haste?
How would you build such a character? Go for Eldritch Knight 10 and then add Wizard or add him earlier? What about stat distribution? I'd really like my character to not be a stereotypical bumbling idiot Half-Orc with 8 Intelligence but someone who possesses knowledge about the world around him and is charismatic enough to come up with some witty answers before cutting you in half with a longsword if you piss him off. I know there's that helm that sets your INT to 17 but it would bother me too much knowing that without it he's a fool.
Any good Feats I could take to deepen my interactions with NPCs?
