Hi and welcome my friend

Glad to see the community growing in these sides.
1.I'm not sure too sure on this one but I don't think the dragon, can walk in dragon form but they can land on ledges and change back into human form.
2.Don't have a clue
3.I think decisions will alter the ending not sure how much it will alter it but its an RPG so any decisions will also come with a consequence.
4.Don't get what you mean.
5.If you mean customize by apperance I don't think you can do anything to the dragon except for skills and armour.
6.Yeah the Dragons can were armour as well.
7.I don't know I'm not a comupter gamer.
Hopefully somebody will be able to answer them better than me!
Hope my post at least helps a bit.
