Hit Falconer 2.
Was so excited.
Reddit said Sonic Strike was a true multihit.
Non crit hits for ~4600
Crit hits for 7073.
Used it on an enemy ~50 levels higher. 1 damage pops up once.
x_____X
Edit:
Its a single hit with a 1.5x multiplier divided into 6 fake multiple hits.
You can see it’s a fake multi-hit in its skill video bro…
Try using it on something actually within range of you character. o_O; And not 50 levels higher.
I did use it on something within range. It was hitting for less than multi shot 10>_<
I just skill resetted and each dive from hovering was doing half the damage of sonic strike as well >_<
Edit: Over half. Also, sonic strike didnt get boosted by lethargy so it isnt strike damage.
The post says 50 levels higher, so I assumed you meant the monster was 50 levels higher than you. Some skills are defense piercing while others aren’t, which may have to do with it, but there’s no reason for it to be dealing 1-10 damage on monsters in you range. It sounds more like a bug than the skill sucking O_Oa
Also, I haven’t gotten falconer but I do level a hunter. If the falcon is anything like the other companions you need to train/level it’s stats up too–that might be why the damage is subpar.
That was me testing whether its a true multi hit or fake. if its a true multihit, i wouldve seen more 1’s appearing instead of just 1.
It does suck that it’s not a true multi hit 
So after running the damage naked and with arde and with weapons, I got the multiploer for this skill to be 1.5x.
Actual formula where all the numbers fit:
(patk - enemy def+skill damage+elem property) * 1.5 for non crit
(((Patk - Enemy def + skill damage) *1.5 )+crit atk+elem property) *1.5 for crit
that’s what you get for listening to reddit
