In previous generations all it did was make ohko moves fail. Now it acts lilke a focus sash but does it still make them fail? is it just a focus sash.
yes sturdy protects you from KO moves which means leave you with 1 hp but only on the first turn
same with focus sash
hope it helps :)
In my memory OHKO moves Completely fail without doing ANY damage whereas moves that arent OHKO but would still take you out will act as focus sash .
