8 hours of no atma

And no you DONT NEED it to progress. Leviathan weapon can do just fine aswell. So dont need to rush it out. It is that YOU WANT it more then YOU NEED IT.
But calm down, you will get it sometime. No need to be Now.

This is only true for patch 2.2. As someone in the Fate forums already said:

Thirdly. In regards to there being other options? Yes you're completely right. There 'are' alternatives than to grind for your Atma weapon. Go find a group. Get your Leviathan weapon, have a jolly cheer. Huzzah! Suddenly when the next patch or relic upgrade quest rolls out. You're now locked out of it because you still have to go back and get those blasted little stones.
