If we were to count how many times Faust fires off a s3-2 we get some funny numbers. Every turn she throws it's basically an entire turn worth of extra damage on her own considering she does around 219~450 damage to every enemy on section 1.
Turn 3 she fired one off for 545. Turn 4 she fired one off for 354. Turn 6 she fired one off against the sloth pecca (giant wall) for 219 damage. Turn 7 she fired another one off for 645. Turn 8 she threw 2 because her s3 gives her assist defense for 258 and 475 damage respectively for a total of 733 damage in one turn and could have fired off another one next turn if the sleeping bag hadn't died lol. A total of 2496 damage not counting damage from her counter which is guaranteed to be used alongside her s3-2 or any other skill.

Just in that one 9 turn section, she used her s3-2 7 times.
There is no ID in the game that gets even close to what she can do. Two IDs that could be close with WildHunt and Sancho(the closest comparison being WildHunt considering he can also do s3-2s on demand) wouldn't keep up with her damagewise not to mention they can't do 2 s3s in a single turn or one every single turn.
