Blocked c.S - 2H (CH) - [4]6S (whiff) - c.S - dash - c.S - 2H - [2]8H - AD - j.S
If you're attempting this in training mode, you can set the bot to block only the first attack. You need to stagger c.S - 2H for 2H to actually land instead of being blocked (which is a very useful skill to know against players)
