caper arknights has such a brazilian portuguese accent it's not even funny lol
i'm claiming her. she's brazilian.
Caper and Rebecca swap
The second one
So if I'm not mistaken, Caper's effective attack interval would be
Start-up animation + travel time to target + travel time to Caper + wind-down animation
I didn't want to speculate on what the ideal distance from Caper was in my numbers because I don't know the animation timings which do matter here. If we assume no animations, I believe it is about 2.808 tiles from her position but I can't really say with any certainty.
Caper Numbers
This isn't necessarily a full fledged analysis (I haven't used Caper all that much since I haven't had the EXP to level her yet), but I love doing the act of crunching the number.
