Use sp1 to build force field charges. More force field charges are better as they protect you if you make a mistake. Dex (dash back ) to become invisible and opponent has vulnerability charges. The more the dexterity (dash backs) more vulnerability charges will deal damage. Try to stay invisible longer by not get hit by opponent/blocking. Use sp3 to build 100 force field charges and when u have lot of force field charges and vulnerabilities use sp2 to see that crazy damage.
