Guard Primers are the multiple bullet-shaped icons lined up under your life gauge toward the center of the screen. Primers are removed whenever you block certain attacks The maximum number of Primers is different per character, and are removed when you block specific attacks (also different per character). When the opponent's Guard Primers are reduced to zero, they will be Guard Crushed. A Guard Crush will leave them completely vulnerable to attack, giving you the chance to land a combo.
- When blocking an attack that removes Guard Primer(s), the Primer will be removed no matter how you block.
- If blocking the attack would reduce your Primers to zero, you can Barrier Guard to retain 1 Guard Primer, but you will lose approximately 1/3 of your Barrier Gauge.
- Guard Primers recover very slowly over time; 625 frames to recover 1 guard primer.
- After getting hit by or blocking your opponent's attack, Guard Primer recovery will temporarily stop. Guard Primer recovery will not resume until 120 frames have passed after hit stun, block stun, or after recovering in the air.
- Whenever you lose a Guard Primer, the 625 frame recovery timer is reset.
- Some attacks remove more than 1 Guard Primer at once. For example the last hit of Taokaka's Hexa-Edge removes 2 guard primers on block. Barrier Guarding one of these attacks when you have 1 or 2 Primers left will reduce you to 1 Primer and consume 1/3 of your Barrier Gauge.
- Guard Primers will be restored to their maximum amount after a Guard Crush, but Guard Primers lost from doing a green Break Burst will not recover until the next round. Characters with a lower number of Guard Primers should be careful about using green Break Bursts.
- Arakune's Astral (n to infinity) will automatically Guard Crush if blocked normally. You can avoid being Guard Crushed by Barrier Guarding, but you will be reduced to 1 Guard Primer, so be careful.
When your Guard Primers are reduced to zero, you will be Guard Crushed. If Guard Crushed while standing or crouching, you will be in a standing state or crouching state respectively, and will be completely vulnerable for 120 frames.
A mid-air Guard Crush will cause wall-bounce, and the player will not be able to Emergency Tech, so you can attack them while they are in a lying on the ground.
Upon guard crushing your opponent, the damage from the next attack with will not incur its P1 proration value, so use an attack with a high P2 value. Note that a 90% damage proration value will be applied to this first attack, instead, but this proration has no effect on the air untechability time. Additionally, throw attacks cannot be broken out of, and since the throw damage will be 100%, characters with command throws should take advantage of this situation.
Guard Primers will be restored to their maximum amount after a Guard Crush, but Guard Primers lost from doing a green Break Burst will not recover until the next round. Characters with a lower number of Guard Primers should be careful about using green Break Bursts.
