Abby's keys

Hello friends,I'm looking for this key but can't find it,I solved the quest and find the mana charger for princess vassila but I didn't get the key also looked at the cave by tapping every statue no luck where can I found or get it?thank you for helping.

You need Live Water to wake the bogatyrs up.
In the Bogatyr Cave in the Strah Mountains the key is kept by a statue in the west (Dobrynia)
In Buran Pass look for Udaloy in the southeast.

Thank you my friend,where can I find live water?

There's a live water well in the NW corner of Krivda Village. You may also find it in other places and create it with the Create food spell sometimes.

What it's mean live water I have no idea what I'm looking for,and where is buran pass I can't find it in the map.

As I hinted already, live water can be created along with food and there's a fountain with live water in Krivda Village
Buran Pass can be found on the world map, it's north of Krivda Village and west from Upper Vazuza (not sure whether "of" or "from" is appropriate here in English lol. Does anybody know for sure?)

Thank you so much,I found it and got the keys,also in Abby's there is a wall with crack,I try to hit but nothing happened.

Cast Lightning bolt on that crack (that's what Vasilisa told you to do)

Thank you very much for your help.i guess I'm so excited to finishing with it I didn't focus on vasilla words.

How does one access/enter Buran Pass?
Thanks

You can enter Buran Pass from the west via Upper Vazuza. To get to the inner pass. Walk over to the snow and walk toward the gap in the rocks. Walk north.
