Seeings as no one has done one of these, I thought I would give it a go. Everyone knows that the Demo sets suck in that they only have Elemental defense. So I came up with a couple of concepts.
Reaper Demo set: http://i49.tinypic.com/xojwjo.jpg
Summary: The concept of this is inspired by the Deadshot set. The look for this set has aspects of that of a Zombie.
Defense Power: The defense stats for this set should look something like this: http://media.spiralknights.com/wiki-images/9/93/Equipment-Snarbolax_Cap_...
Resists: Seeing how this set is mostly Zombie proof, let's add high fire and stun resist. I chose stun and fire because Dust Zombies and Slag Walkers are the two Zombie types we encounter the most.
Bonuses: Both the cap and suit would have Damage Bonus vs Undead Medium and CTR Medium.
Mats to make: The required mats for alchemy could look like the ones of Volcanic Demo (http://wiki.spiralknights.com/Volcanic_Demo_Suit), except for two changes; Instead of Red Shards, Dark Shards; and instead of Volcanic Iron, Reaper Rib.
Void Bomber set: http://i46.tinypic.com/2vdpg5u.jpg
Summary: I once saw a request for Void armor sets, which inspired me to come up with this. At first, I wanted to color the set to match the color patter of the Snarbolax set, but I decided not to because Void and Snarbolax aren't the same thing. Armor set is black like the Snarbolax set, but instead of the orange-red, I decided to give the detail a Prismatic value. Void monsters are supposed to be OP, so I made this armor semi-OP, but with lots of defects to balance it out.
Defense Power/Resists: Let's go ahead and give this set the same Defense/Resists as Mad Bomber. Instead of Elemental Defense, Shadow Defense. http://media.spiralknights.com/wiki-images/a/ac/Equipment-Mad_Bomber_Sui...
Bonuses: Both cap and helm would have CTR Medium, Damage Bonus Medium, AND Movement Increase Low.
Mats to make: I was thinking of giving this set the ability to use Nightmare Mane, but I know it's too controversial. If a SL mat were used on this, then this could become a SL set, which I know most of you will hate. So let's use these mats for this set: http://wiki.spiralknights.com/Graviton_Vortex
Shadow Bomber set: I got no concept for this, but this set would basically look like every other Demo set, but would be colored a deep purple color, like that of the Purple Rose set. The helm would have Prismatic Glow Eyes automatically added to it and the suit would have a Shadow Aura, like that of the Acheron or the Dread Skelly Shield.
Summary: Basic Demo set, but with Shadow Attributes.
Defense Power: Would be similar to this, but with Shadow Defense instead: http://media.spiralknights.com/wiki-images/1/1e/Equipment-Bombastic_Demo...
Resists: I know these could be utterly useless, but lets give this set Curse and Poison high.
Bonuses: Damage Bonus Medium and CTR Low for both cap and suit.
Materials: Similar to those of the Mad Bomber, except switch Reaper Rib to Shadow Steel. http://wiki.spiralknights.com/Mad_Bomber_Mask
Well that's pretty much it. Please leave feedback and thanks for taking the time to check this out.
-Reaper Demo is bad in general, just as Deadshot.
-I dont think low movement justifies the reduction of ctr and damage of Void over Mad. Altought triple bonsues is new. Still there are no valid excuses to create something "semi-OP".
-Shadow Bomber simply has too many bonuses with no drawbacks. Compare it to that Bombastic you copied stats from...
And no piercing?
