how do you make all act cache with bonus?
can i just do every quest without taking any cache?

Except act 3-4 they happens to glitch a lot so do not finish 1 quest on each act 3 and 4

Then take talk to tyraels in each act in order he is giving you

You can do all the quests from act 1 - 5. after you turn in the first bonus it will randomly select a 2nd bonus. 3rd. etc... When you do Act 3 & 4 leave one quest up on each because since they are in the same town the bonus will glitch.
