Platinum Coldain Insigna Ring

[TheBlob]

Hello everyone,

So my friend helped me kill Ghrek Squatnot but, after the fight, it appears that Tain was dead (he was not there anymore). In all the action, we didn't see what happened.

I logged in today and Tain was up. When I gave him the Frozen Elixir, nothing happened. He didn't say he did not need this item, and he didn't give it back. My question is: Is the quest still possible if Tain dies? If so, do I need to tell the new Tain "I will help", and give the "being helped version" the elixir before the new giants arrive?

Thanks for the help!
