Quest - rescue the elves

How did everyone beat this quest!? It’s annoying cause they just keep multiplying when i almost defeat them all!!

This is my team atm

Defeat the ones that have yet to clone. Not the ones that have cloned already.

Finally beat it thanks to this guy and his skills!!

I don’t understand how to beat it it’s like I kill the.middle and top one then clones happen then top and bottom clones happen I don’t understand what to do.
