Well this is just an idea I have for an item and it's art.

The Scarlet Shield currently has no modified art, or as far as I know, modified stats, in any of the updates.

I don't think you can acquire the recipe any more either, but I can't confirm this.

Since I liked the idea of the Scarlet Shield but it appears it may be disappearing, I'm going to offer up some ideas on how it can look and function to keep this newbie friendly shield alive.

Scarlet Shield ~ ★☆☆☆☆

Appearance: A red shield, the same colour as the Tier 1 Hearts. It's shaped like a Shoshinsha Mark, but less angular and maybe a bit more rounded, to make it fit the shape of a heart more. It has a red core with a glossy, darker red outer layer. The dark outer layer acts as a see-through outline for the shield.

Stats:

• 15% of the Normal Defence bar at level 10.
• +1 Health

Scarlet Defender ~ ★★★☆☆

Appearance: Almost identical to the Scarlet Shield, except it has a very light red outline around the outside of the dark red layer. It also has a beating animation.

Stats:

• 50% of the Normal Defence bar at level 10.
• +2 Health

Arch of Aorta ~ ★★★★★

Appearance: Very much the same as the Scarlet Defender, but the outlines are larger. There is a light red heart symbol in the middle of the shield. It also has little wings, like the ones that appear when you revive somebody or the ones that used to be either side of the Omegapods, that gently flap when the shield beats. When the shield is on your back, the wings fold back at an angle as to not clip with shoulder pads or arms when moving.

Stats:

• 75% of the Normal Defence bar at level 10.
• +3 Health

I guess if by the descriptions, this shield is too hard to imagine, I may draw some crude imagery to go with them. But I don't think it should be that hard to understand.

It may need reduced defence as well, but as the majority of 5-star shields have full defence, I think that 20% of the bar will be enough of a trade off in the long run.

EDIT: I had some ideas for corresponding set pieces!

Armour

Well, we already have the vitasuit, so I might just modify that a little bit to fit with the Scarlet Shield.

Vitasuit ~ ★☆☆☆☆

Appearance: It would be like a rounder looking set of Plate Armour. It would have big, round Pauldrons and no Gorget, and less seams in the armour, with leaf shaped Culets and Fauld. The legs would be about the same, just with pointer feet.
It would be silver in colur, with a big, shiny red heart, stamped onto the chest.
The heart would display the number of life bars you have inside it, like the heart next to them.
So if you had more than 20 Health bars, the little heart would have a 1 in it.
The parts that use the player colour would be underneath the armour, so not very much is visible.

Stats:

• 30 Normal Defence
• +1 Health, becoming +3 Health at level 10

Vitasuit Plus ~ ★★★☆☆

Appearance: It would be very much the same as it's previous incarnation, however the armour would be a lighter silver. There would also be a plus on the belt buckle, in the player's colour.
The heart also gains a small, pink border around the outside.

Stats:

• 70 Normal Defence
• +4 Health, becoming +6 Health at level 10

Heart's Wall ~ ★★★★★

Appearance: It would be almost identical to the Vitasuit Plus, but it would be much lighter silver. The heart and plus both glow, the heart also gets a shiny, glossy coating.
It also has a thick, red scarf around the neck.

Stats:

• 130 Normal Defence
• +8 Health, becoming +10 Health at level 10

The armour is probably OP, but the only bonus it offers is extra health. The Defence numbers will probably need to be reduced significantly for it to balance out well, but since it only offers defence to one damage type, it should be fine.

Helm

This is pretty damn cool, if I do say so myself.
Even if the rest of this stuff doesn't happen, the helmet needs to.

Vitahelm ~ ★☆☆☆☆

Appearance: It's the same silvery colour as the Vitasuit's armour and it looks similar to a Mechaknight Mk I's Helm, just without the additional faceplate. It's sort of squarish and the eye slot emits a dark version of the player's colour, like the one on the armour's spots.

Stats:

• 30 Normal Defence
• +1 Health, becoming +3 Health at level 5

Vitahelm Plus ~ ★★★☆☆

Appearance: The helm starts to shape up a little, it's beveled at the top, with rivets along the crown and it's colour is the same as the Vitahelm Plus'. The eye now emits the right hue of the player colour and on the very tip of the helm, you can see the exact number of health pips you currently have.
It rounds up, meaning it counts halves of health. It's in the same font and style as the one that appears on vitapods.

Stats:

• 70 Normal Defence
• +4 Health, becoming +6 Health at level 5

Omegahelm ~ ★★★★★

Appearance: The helm is the same colour as the Heart's Wall now, a glow appears to be coming from the eye slot. There are also small wings like the ones that used to appear next to Omegapods, floating either side of the helmet. It looks almost identical to a vitapod in form, now.
The wings flap in time to the wings on the Arch of Aorta.

Stats:

• 130 Normal Defence
• +8 Health, becoming +10 Health at level 10

Set Bonus

Wearing the whole set increases the chance that you will get hearts from bushes and other breakable items.
It also increases the amount of health you gain from using pills by a small amount.

Obviously, all of this stuff probably isn't possible.
I didn't add anything like tooltip descriptions or recipes, because those things don't particularly bother me in the slightest.

EDIT 2: Changed the stats and the Vitasuit tree just a leetle beet.
