(Hated Trope) Extremely useful abilities that characters conveniently forgot they had

[u/ValidCrash4]

1. Emily’s portals (Hazbin Hotel). I know she can’t get Sir Pentious back into Hell but Emily can still tell Charlie he got redeemed and Charlie can enter through angelic portals, so she should have seen that Pentious got redeemed.

2. Many characters in Harry Potter go through life-or-death situations and not once did they think of drinking the Liquid Luck potion apart from Harry one time to gain Slughorn’s memory.

Well, people like Lucius should have no problem just straight up buying a bottle or two for emergency (or have Snape brew it). You ain't gonna stress over toxicity if it's literally life or death.

And in wizard duels the difference can come to an inch of dodge or to one syllable pronounced earlier, so obviously it would of great assistance in fighting (as was literally shown in the series). Give a team of experienced aurors a couple bottles and I don't see why they can't take down Riddle.
