you start with something you can fully customize at the boat part of the game.' I tried it with a quick save and asked for an archer and got some elf, but you can then take that elf to the mirror and fully customize him so basically as long as you pick the race you want + some base skills so you get the correct starting books.
You know how when you get an ally you can spec a new spec for them? It's same type of menu, only you just get some random dude. IMPORTANT EDIT: '.there is a girl on the boat that offers you more companions for 900 gold.
My only question is if this remains available to you throughout the game? What surprised me is you can even adjust the look of your character AND the companions! RIGHT at the beginning of act two you will have the option to fully respec every aspect of your companions and yourself - abilities, talents, skills etc. I see this get asked and I too asked as well.
