Guide to Sword Anti-Vanish War Tech
By tea.
(Only works with Tapion, Future Trunks and Sword Trunks). This tech allows you as the aggressor (?) to avoid vanish battles and get the upper hand on the opponent.
To execute this properly you need to press the dash button like you would the vanish button, just slightly earlier. (A on X-Box, X on PS).
How to Do It
Here is Trunks about to land a hit on Tapion, but he will vanish this attack, usually forcing a vanish war – but with this tech we can now avoid this.
At this point you press the Dash button, in this example, Trunks did it 9 frames after Tapion appears again from the vanish. (Slightly faster than the normal vanish timing).
Holding down this dash button causes trucks to avoid this next hit, and put him in a great position to counter.
At this point, you can attack like normal, while your opponent is still stuck in an animation.
