Arknights CC#2 Abandoned Factory Risk 30 (Ballista Lv 3)

CC4 Blade Permanent Stage
I'm so tired of this method.
I needed Red's stun. I deployed Manticore so that she don't get hit from ballista, but she cannot affect enemies right the tile just in front of Weedy.
I think Angelina skill level that is enough to rotate with Weedy S3M3 at the same time without Manticore is less than lv 4.
