The ink sword (Hopefully in splatoon 3) Info in comments

Hmm. Seems cool.

That could work

not my best, but yeah! you could do a duel with your friends and parry like in botw

Mhm, also parrying was a thing way before breath of the wild, Parry is also used in sword fighting as another way of blocking attacks

yeah. and the armor could be resistant, like chainmail irl

Nah, I think it should be chainmail and platemail in one gear to represent the medieval ages in one set

like this?

Yeah, like that

alright, but like squid stuff?

Yep

cool

Thanks, I love swords a lot so seeing a ink sword would be amazing

It would be neat, but I guess somewhat violent

That could be true and I have a failsafe, the sword is made ink so it is unable to cause bleeds or any visible wounds on inklings

Alright, so like a kids foam swords properties?

Yeah, like that, I'll make the Sheldon dialog for this thing to keep it rated E10+

it would go well with the knight armor

Yeah!!! Maybe we could make it ink sword and ink shield

Maybe like a tower shield or something
(I tried my best to make a tower shield)

yes! like link

Or like the medieval ages

Imma draw that soon

Main weapon, regular grip)
The ink sword is another one shot weapon on certain conditions, the ink swords tip will one shot but has the worst control (control = hitting rate) the middle of the sword can 2 shot an opponent but with main weapon power up it can one shot and it has a moderate controlling, The mantle of the sword is the least strongest part of the ink sword but It has the most controlling. The regular grip is just as slow as the Splat roller or Dynamo roller but it hits hard, with maxed Main damage, The weapon will one shot.

(Sub weapon, reverse grip)
For the sub weapon, you go in reverse grip instead of a bomb. The reverse grip deals less damage as the tip 2 shots an opponent but has high controlling, The middle 3 or 4 shots an opponent and it still has moderate controlling, and the mantle will take 5 hits to splat an opponent and has a low controllablity. The reverse grip is faster then the regular grip making it a great way to charge up your special.

(Special weapon, takes 190p to generate)
The Phalanx is a defensive special weapon used to defend the user, This special has a quick start up time and is perfect for rainmaker or tower control however your back is left open for attack, The Phalanx's shields can take a lot of damage for the shields to crumble, this special isn't as powerful in offensive power as the spike on the shield don't deal as much as the main weapon does.

(Summary)
In all, this regular grip is perfect for close combat encounters while the reverse grip is more suited for gathering the special then it is for combat. The special is perfect for protecting teammates in the tower and escorting your teammates in rainmaker mode. The Inksword is heavily based off of European greatswords from the medieval era as it has the same range as a the brushes but has the strength of a roller.

(Sheldon's Dialogue of the ink sword)
"Atlas, thou have presented thy INK SWORD to thee warrior. The ink sword excels in close range combat but is quite lacking in far range and this weapon has two grip options but first let's talk about the main grip. The regular grip is dominant in battles as the tip is where you always want to take the point from the opponent. But if your more in for inking the stage then splatting then press R and you'll do a shield bash, the shield bash will launch the user forward and slam into the opponents with an inky bash, this is good for escaping tough times or ambushing an opponent. And let's not forget the special weapon the phalanx, Press in R to activate the Phalanx as ink shields tougher then the Tenta brella's brella appear, I only see this special's use for Tower control and rainmaker battles. But if you want more new generations of weaponry, look no further then the ink sword, also don't forget that you can use the ink sword and ink shield together for maximum power"
