Impeccable Yet Perilous Technique

''You get a super powerful attack, but you have a 40% chance of that attack greatly injuring you. Would you still use it?''

The super effective technique that is bound to succeed but also comes at a risky price of greatly injuring or even killing its performer. It's up to the Main or Hero to attempt the Impeccable Yet Perilous Tactic to complete whatever task they're currently assigned as all other approaches at completion will only fail. When it's finally time for them to do what it is they must, the main character steps up and readies themselves to use the Tactic. Apply Dramatic Slow Motion when the Tactic is put into action for suspense that will be ruined by your knowledge of how the MC will, at the absolute worst, get very injured for executing the Tactic and have to be hospitalized later.
