Flash knight is the Floor boss of the first floor, Dream.
In Phase 1, the Flash knight has two attacks.
- Swings His Sword, Causing A Sweeping Motion of bullets, and 4 pillars at certain angles.
- Fires His Cannon, Creating a massive Splitting Shot.
In this phase, Flash knight loses his body and has only one attack, Where he teleports near the soul and swings his sword at it.This does Not Create any bullets, but will deal Very High Damage if the sword makes contact with the soul.
In phase 3, a heart is revealed. This heart is usally covered and any attacks that hit it will deal no damage and will be countered with a shotgun blast. it has also only one attack where it shoots shards of it's shield in all directions, and boomerangs back to the heart. killing this phase will cause the game to transition to Feel, the second floor.
Try to stay far from the flash knight. His sword attack fires Tons of bullets to be shot, but is easy to squeeze through as long as you are not around the high density rows that it creates.
The cannon isn't a threat, just stay as far from the shot as possible.
Stay FAR away from the range of the sword. Never tank the hit from it, as it is very deadly and will probably eat one of your hearts. Stay out from the swords range, teleport if needed. you can run away from the sword at base speed without needing to teleport. remember to still have the flash knight in range of your weapons.
At this point, the fight is over. It's only attack is very easy to dodge, and will only create shotgun blasts when you hit it's shield. just be patient and you have this in the bag. No sweat.
