Hey guys!

A quick tip for those who may not know about this

I remembered about it recently when I was doing breakthroughs on my Edo Sasori

So basically you can save protection vials on ninjas who have L breakthroughs because they always come in pairs (for example mystery and standard) and 1 cannot be changed without the other

Example:

As you can see, I locked only the mystery and didn't lock my standard attack

It does ask you if you are sure because you have an "orange skill" but just agree to it

I did it 4 times for this screenshot and the unlocked standard attack never changed (but I actually did it 100 times more after that so no worries)

and that basically saved me around 100 protection vials
