the problem probably isn’t the general power drain but foxies drain. She consistently attacks 4 times on 4/20 but each time she goes it does more starting 3 than 6, 9, than 12 which as it happens it too much to deal with if it happens too early
I had wrote a hopefully decent guide with tips I used to beat 4/20 in a reply to a prior person maybe that will help I don’t want to re type that whole thing
