Appearance[]
It is a sword with a light to dark crimson gradient to the blade and has a red handle with a silver end. The middle features a silver striped guard with a gem in it. It also emits red 
Sparkles that will appear on the avatar while worn and equipped in-game.
Function[]
When in-game, the user can click once to swing the blade, or double click to Lunge and strike forward horizontally to their mouse/touch location. As an extra effect, while lunging with the sword, it will leave behind a trail of light red waves behind the blade.
Unique Ability - Crimson[]
Pressing Q will summon five red spots on the ground to appear around the user. After 4 seconds, the spots will turn into pillars of lasers and spin in a circular pattern around the position of the user whilst converging back into a single column. Any players/entities hit by the lasers' sourspots (tips/edges) receive 70 damage each, while the main laser will delete most unanchored parts and players after a distintegration animation, this can be useful to block projectiles such as the Flaming Hedgehog Cannon's hedgehogs. The ability has a 12-second cooldown that engages after the pillars despawn. Crimson is very powerful for map control and edgeguards as the pillars are very hard to challenge via evading their pattern or beating the lasers which is really hard to do.
Tech Skill[]
Using Rainbow Periastrons' Singularity, you can use Crimson and Singularity at the same time to perform a Crimson Kill Confirm, this uses the black hole to pull in others while the black hole despawns right when the crimson pillars close in, this trap requires gears like Bat Knight Bat Sword to get out of.
Using Chartreuse Periastrons' Deflect Barrier, you can reflect the pillars sideways and fire them up or down depending on the autoaim, this is known as Crimson Tilt. Reflecting the pillars autoaim from going through the Baseplate/Map can keep them on surface and cover lots of area, depending on the horizontal autoaim you can stretch the pillars to reach even further. Performing Crimson Tilt to fire upwards can stop the landing projectile strategy noob opponents commonly use (camping directly above the opponent and them dropping down and performing a landing projectile with gears like Flaming Hedgehog Cannon to get close up kills, you can easily block off escape routes via this setup.), reflected crimson pillars will either force the opponent to go very high upwards or go to the side giving up their strategy allowing you to easily get out of the strategy by either gaining height or running another direction opposite to the opponent. This can also be done by welding Remote Explosive Detonator's C4 to a pillar
To Edgeguard an opponent, hit them off the map and use Amethyst Periastron's Comet Crash, they will be forced to return to the map, when they are offstage place Crimson, this will threaten the opponent from getting back on via flying straight back and will give comet crash more time to debuff their flying gears, if they do get back on the normal way, then they will die to crimson, if they manage to clutch it and get back on the map, they will be in a very bad spot, use knockback options to either hit them back offstage or into the crimson pillars, if they use an anchor gear to counter comet crash, you can crimson tilt to reflect downwards (if other players are around, try client freezing to avoid reflecting the beams to surface level) and this will edgeguard or put even more pressure on the opponent using the anchor strategy.
Trivia[]
This section is a trivia section. Please relocate any relevant information into other sections of the article.
- The item description was changed on July 9, 2021.
- The original description was "This sword men use to fight angry narwhals... in space.".[1]
- Similarly to Rainbow Periastron Omega, if the ability is prevented from finishing by means such as Catalog Heaven Remake's cleanup or a strong lag, the ability will go into permanent cooldown. It is possible that Takeohonorable previously had a countermeasure that set Crimson's cooldown down to 5 seconds in the event this happens, but if so this countermeasure does not work as of now.
- KOSS Wind Summoner can break the animation of the ability, causing the pillars to fall straight down.
- If you die/delete the gear while Crimson is active, the animation will be broken depending on when you died (during windup or during spinning lasers)
