I've just unlocked the weekly quests and done 2, I got 16 Simurgh feathers and it unlocked several temporary craftables. Which armor chests are worth getting? The helmet, armor, or axes, boots? I dont want to waste them as it will be a whole week until I get more and its not guaranteed I get 16 again. The reptile eyes are rather difficult to get too

Im at the point where every UA i make a steady few Sd coins, and 20-50 Billion SP every ascension, and I've collected a few astral keys. But how in the world do I break the wall to get in the trillions with SP, I cant unlock Colo and Higgins quests because they also cost coins in the St's, how do I break the wall from Billions-->Trillions, and Sd-->St?
