Singular Focus is a new Atlas Keystone Passive Skill.
Flavour text: You fancy yourself a god. You see only what you want to see.
The Singular Focus keystone makes it significantly more likely that your Favoured Maps will drop. If a map drops that is not one of your Favoured Maps, it will be converted into a random currency item. This means that you’ll exclusively see your favoured maps and outside of that, more currency. This is the realisation of the “I only want to play one map” dream that some players have. It also helps players who are over-sustaining maps and would rather get extra currency items.
