Most efficient way to create food?
At the moment I've levelling up 1* food to 2*, then these 2* to 3*, then these 3* to 4*, all by running in 12-3 on hard mode.
However, is there a more efficient way of levelling up food, noting that with my main champion still on 5* I can't do 12-3 Brutal yet?
Also, what's the best way to apply brews? I'm just using them to top up food a bit at the moment.
Any advice very welcome, as I'm not sure how long I'll have excess energy enough to keep levelling food at any reasonable rate.
