Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems A trial for all seasons

Is this quest uncompletable without an elf? I activated all the totems, and got a confirmation in my quest log saying that I got attacked yet nothing happened.

It should be. Please email supportdos2@larian.com, with a description (or link to this topic) and your latest save (or a Dropbox or Google drive link, etc), and (if available) a save before first speaking with the brazier.
Each save is a folder in the '..\Documents\Larian Studios\Divinity Original Sin 2\PlayerProfiles\<ProfileName>\Savegames\Story' folder.
In Windows Explorer you can zip file(s) and folder(s) by right clicking on it/them and selecting 'Send To | Compressed (zipped) Folder'.
