Hi. I'm stuck in the Ice Temple in chapter two, that's just after your air ship crashes. I'm on the second level and I've explored everywhere except two rooms, one is Oria's bedroom and the other is a room that mentions a withered sliver of a great tree branch can be seen encased within.

I've read a walkthru and it says to use the painting on the first level and say In "Auril's name from winter's veil... " but that option is not there. I believe Nathaniel's Ring of the Ram is in there which he needs in order to escape (and thus for me to escape).

The second problem is I need to defeat all three priestesses. I've got all but Oria. Do I really need to complete the battle squares in order to get into her room? It seems like a real drag. Plus I don't think I'll be able to do it.

Any help will be appreciated.

You only need to win one battle series at the battle squares in order to get a key (3 squares in a row at lowest difficulty is sufficient) to get a key for processing, the remaining battles are optional, can be still done in chapter 4 as long as you're still able to walk back there and only yield useful loot.

Nathaniel doesn't need his ring of ram, his bag of holding is sufficient for him to start the next chapter. But you get more XP if you give both to him.
