I've been on the same "Sealing The Blade part ", though I have been repeatedly doing the 300 light strike correctly. It shows that I killed Heolster, but that I haven't defeated Alak-Hul. Please help, I just want my dark drinker.

You need to kill the knight AND Alak-Hul in 30 sec or less. Kill the knight first, then Alak-Hul. If you kill Alak-Hul first, you will not be able to kill the knight.
