anyone knows how to get the thunder blade for the panel mission?

It's a random drop from the Fenrir gate keeper. Killed/assisted in like 8 and didn't get any yet.

That one was a pain to get. You then have to get it to Thunderblade** for the next panel board.

You can get them from running the trade system but that requires unlocking that feature first by completing story missions.

Ty. Thought it would be something easier to obtain, since the others panels were completed relatively fast

Alternatively, the Thunder Blade is also a potential reward from one of the first tier trade routes.

Currently just over 300 eggs - far far too grindy I'm what little 15% of the way

What determines the number of eggs you get for completing the stage? Sometimes I get 15, sometimes a lot more.
