Vacuum Wave Timing Help

[mosaicex]

As other have said, you have to wait until you're actually sliding then use Plunge to prevent it.

I found that staying inside Exdeath's target circle really helps (gives you more time to use Plunge during slide)

This. As a longer knockback, you get pushed out of Plunge's effective range much sooner. You have 5 yalms less in range to work with than other players with gap closers, so you need to be as close to the knockback source as possible.
