It's something that if you rush for you'll probably get burned out on, so instead you should sit back until they day comes where you do "Oh hey I have 25k seals and 9 beast tokens."

...

OH WAIT

Seals and tokens are they only reason to do caravans and hamlet content, and relic weapons are the only reason you would want to get seals (beyond maybe some gear) and tokens. So it looks like there's no reason to do half the content except to get relic weapons.

That being said I'm still shooting for mine.
