Grimm

Hunter's Journal
After the Grimm Troupe has been summoned, Grimm can be found inside the large building at the center of their setup to the left of Dirtmouth. Inside, after talking to him, he gives the Knight the Grimmchild charm. After collecting three flames, he upgrades the charm to the next level, and after collecting three more, the Knight must fight Grimm.

Behaviour

 * Before the battle Grimm will bow. if the Knight hits him while bowing, Grimm will screech at the knight and will counter attack with the flame spawner attack.
 * Firebats: Grimm opens his cape and one or three red firebats are summoned out, flying in the opposite direction with slight homing onto the Knight.
 * Dive Dash: Grimm appears near the top of the arena, turning his body into the shape of a screw, diving towards the ground, then dashing a long distance in the direction of the Knight.
 * Dash Uppercut: Grimm appears at one side of the arena, dashes at the Knight, and uppercuts into the air, disappearing, and leaving behind six flames which fall to the ground.
 * Cloak Spikes: Grimm's cloak drives into the ground, and summons spikes made of his cloak around the arena, which rise up to near the top of the arena.
 * Flame Spawner: Grimm puffs up his body into a red sphere, floating in the center of the arena. He spawns red flames which can some out in several orientations.
 * Evade: Occasionally if The Knight gets close to Grimm before his grounded attacks begin, he will scurry away and then do an attack.

Tactics

 * Grimm is one of the fastest bosses in the game, and his health scales with your nail upgrades, making him a tough foe regardless of experience or progress.
 * Use the Shade Cloak to dash through both of his Dash attacks (Dive Dash and Dash Uppercut). The Knight can also damage Grimm this way if they have Sharp Shadow.
 * Standing directly next to where Grimm explodes into fire when he uses Dash uppercut is a good way to avoid all 6 projectiles as they spread in a cone pattern.
 * If the Knight stays near the the right/left side of the screen and light tap jumps, they can mostly avoid the flames during Grimm's Flame Spawner attack.
 * During the cloak spikes attack, The Knight can use the time to heal an extra mask. This is easier to do with Quick Focus.
 * Double jump and dash over his Firebats, and you'll be in range to attack.

Trivia

 * At the beginning of the battle, if Grimm is attacked immediately, he will scream and immediately start his Flame Spawner attack.
 * Grimmchild is only required for the first battle.
 * When Grimm perform the Firespawner attack, the theme gets more dramatic by adding chorus to background.
 * The audience watching the "passionate dance" gives ovation to Grimm every time he performs Fire Spawner or reforms after stagger.
 * When Grimm reforms after stagger, he is accompanied with a drumroll
