I tried to take a single MM feat of level 1-4, to fully use UM class features. Looking for ideas on the open feats and general advice on the build.

Also looking for a good trade-off for my familiar (i don't like familiar, just personal taste), PHB2 option seems the best one but still looks sub-par.

There's a flaw (Forlorn) that straight up gives away your familiar. So that's easy.

I don't think flaws are allowed in this game but i'll check with my DM

Also i'm thinking about adding "invisible spell" to the list, wich could be amazing in conjunction with the "false theurgy" skill trick.

Edit:
Flaws are out, skicll tricks are out, so invisible spell is out too.
