Need Help On Focus Lens

[Acculiterary]

So I chose Zenurik when I completed the Second Dream. Didn't know what the schools were until further study, and seeing as Unairu has extra defense capabilities which would go great with my Chroma Prime setup I have some confusion on what I should do to get the Focus School activated. Since Zenurik Lens gives Focus, is it ONLY for Zenurik or can I also use that Focus to open other Focus Schools, which is about 50k to do so. If I bought a Unairu Lens and earned Focus with it, would I be able to open the School or any Focus would be actually gained from it? Thanks in advance.

Each lens earns focus towards a specific focus school. If you'd like to expand to other schools you'll need lenses for those schools just as you guessed.

TL;DR

• Focus trees other than the one you start with cost 50k focus to unlock
• You can only have one active tree at a time
• Nodes marked "way-bound" (which focus on increasing the Operator's base capabilities) are added to all other trees when maxed out
