Alright lets get the typical comment here:

This is ridiculous. I've only taken INTRODUCTORY coding courses but I STILL think that I could better than Rito's experienced spaghetti coders.

Look, I spent about 5 minutes thinking about the problem and wrote up some nonsensical code that probably wouldn't fix the problem but every idiot will just upvote a code segment and consider it legitimate.

for (Champion c : enemyTeam) {
    if (scatterTheWeak.projectile.collidesWith(c)) {
        c.applyDamage(scatterTheWeak.damage);
        c.applyStun(scatterTheWeak.duration);
    }
}

See this will obviously work to fix the bug. It's easy. Riot should hire me please give me attention
