how many points do I need to have before opening the door in eliv thade to get a score of 1200+ points?

I want to get the avatar but i dont want to do a lot of extra anagrams as im afraid i'll lose then..

Edit:
i opened the door when i had 1057 points, when i send score it said i had scored 1407 points, that means you can cut it out MUCH earlier

Someone can lock this now. I hope it can help others in their quest for the avatar.
