Performing 8 Way Run Attacks while moving in any direction

Post GI Strategy
Abare
Abare is the concept of attacking while at minus frames. This concept is not unique to Soulcalibur, but it is worth mentioning as an especially valid option in Soulcalibur 6 because the presence of GI (and evasion) means it’s a moderate risk for the player with advantage to use an attack. Moves with evasion, such as tech crouching and tech jumping attacks, can be great to interrupt your opponents mixup or evade highs/low attacks. The frame advantage from fast attacks is also quite small, so mashing a fast attack while at minus frames will eliminate the opponent’s slower, more threatening mixup options. Mashing at minus frames will also condition the opponent to use frame trap options, which in turn can allow the defender to capitalize on the use of guard impact.
