The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Something good against a mob will usually be an Area of Effect attack.
I'm not sure that there's any trope for weapons that are good against single targets as that's usually the norm, whereas there's a trope for (normally) single-target weapons getting multiple kills in one shot — One-Hit Polykill.
When it comes to a Boss Battle, they come in so many different styles. What works great against a Damage-Sponge Boss might be useless against a "Get Back Here!" Boss. It's hard to say that "This weapon works against all bosses everywhere."
Edited by KDI my case, the character has an ability that increases its damage output if there are no more than 1 enemy at the moment.
Perhaps Situational Sword could fit, but here I'm asking if we have something more specific.
"When it comes to a Boss Battle, they come in so many different styles. What works great against a Damage-Sponge Boss might be useless against a "Get Back Here!" Boss. It's hard to say that "This weapon works against all bosses everywhere.""
What I meant is that "something is more effective against bosses/single targets than multiple targets". Or vice versa.
Weapons, characters, or other tactics in a game that works better against either multiple enemies (i.e mooks) or singular ones (usually bosses).
Do we have something like this?
