My friends crash ability goes like 2 meters far

I personally never had this problem, maybe this is because he has thermo fist?

out of combat? thats normal
in combat? no idea

It’s a cone hitbox.
If you have a person that is not in a party with ff off in that cone, it goes usual distance. If not, you go 2 studs or something and stop.

You can also negate this cone hitbox by climbing then crashing.

you need to aim dash based attacks towards an enemy
