When I did the Seraphynx Sprite mission, I really liked it. I thought why not make a DLC? A cursed themed Shadow Expansion Pack. I'll try not to make this too long otherwise I'll bore people to death. I know you're proably thinking that we don't need another Tier 3 Shadow Boss, but please give it a chance!

Stallos wants to kill every Knight, Sniper, and Stranger. He used to be a part of the Spiral Order, but he went in the Arcade alone and was never found again. The Spiral Order presumed he was dead, until they heard about his plans to kill everyone. Stallos needed assistance and called for it at the time. But the Spiral Order never came looking for him. He died and came back as a Zombie. He felt betrayed and swore revenge. That's when he built up his army of Zombies, Kats, Howlitzers, and Trojans. He is aware that Tortodrones do not exist anymore, so his masterplan is to bring back the Tortodrones.

So there would be 5 levels, and the boss would be called: Stallos (First idea that came to my head), all of these levels are Depth ??? (Note that you can only play 4/5 of the levels as level 3 is a multiple choice between 2 levels).

Level 1 - Search for the Switch

This level is about finding the Control room for the Haunted Train. You take an elevator down to Level 2 and find it at the beginning of it. (Elevator goes down).

Level 2 - The Dangerous Journey

Once you find the Control room (at the beginning of this level) and activate the Haunted Train, Stallos realises that you're in his fortress and closes the doors behind you. You must take the long route back up to the Ground Floor. Only Problem is, is that you're at the other side of the Station.(Elevator back up) This level is swarming with Static Souls. Unfortunately at this point, Stallos has finally finished creating a Tortodrone template. He is now duplicating them fast!

Level 3 - The Restless Sprits Return

Stallos opens up hatches which are scattered around the Station so the Souls can come up. Your job here is to seal up the Hatches to stop the Spirits coming up and Disable the Curse Floor Hazards everywhere which Stallos has enabled. These hazards go on for a while and you won't be able to survive running through them. On your way, you finally reach the Railroad. By this point he has built up his Army of Tortodrones which he plans on killing everyone with.

At this point...
There are 2 separate Carriages. The one to the left will take you straight to Stallo's lair where you shall kill him once and for all! But Tortodrones will wipe out nearly all of the Spiral Order, all the Strangers will be gone, and Snipers will become extinct. Or you can take the Right Carriage and destroy his Tortodrone template and wipe out his Tortodrones and destroy his Fortress! But he will escape and Survive...The choice is yours!

Level 4/1:

Stallo's Lair:

You will fight Stallos in a Spooky themed Graveyard where he can Summon Trojans, and invincible Howlitzers. He attacks with a Shadow Version of the Leviathan Blade. It's a Grey Sword with Dark, Purple energy flowing through it. A 3 Swing Combo Sword, you want to keep your distance!

4 Phases:

Phase 1:
You have to break all of his remaining Spiral Order Gear off (He has Azure Guardian Set), enough damage and it will fall off!
Tier 1 - 2 Zombies appear
Tier 2 - 4 Zombies appear
Tier 3 - 4 Zombies + 2 Spookats appear
He avoids your weapons by dashing out of the way. It only takes 6 seconds for his Dash to come back.

Phase 2:
This is when he is most Vulnerable, he is resistant to Normal and Shadow Damage! Pure Piercing or Pure Elemental is the best here. He can also Shield bash into you and stun you if he does. He avoids your weapons by dashing.(6 seconds) His Sword is much much weaker (like the amount of damage you do to the front of Arkus)

Tier 1 - 2 Zombies appear
Tier 2 - 2 Zombies + 1 Trojan appears
Tier 3 - 2 Trojans + 2 Spookats appear

Phase 3: Is a repeat of Phase 1 apart from he uses a Spark of life to revive himself (Sorry I know this might be a little bit like Arkus, but come on, he was in the Spiral Order!). This time he revives with Almarian Crusader Set, the darker version of Azure Guardian! So phase 1 he is resistant to piercing, Phase 3 he is now resistant to Shadow damage.

Phase 4: This is when the indestructible Howlitzers come in.
Tier 1- None
Tier 2 - 2
Tier 3 - 2

Also 2 Golden Trojans will appear, only in T3.

This time you have to repeat Phase 2, apart from you got 2 Golden Trojans on your back and Stallos is still resistant to Shadow and Normal damage. He has slightly more health than he did in Phase 2 and once he is killed, a gate to your left will open and you receive a unique Material (depending on what Tier).

T1 - Zombie Dust (1*)
T2 - Zombie Bone (3*)
T3 - Zombie Soul (5*)

There will also be Vise at the Mission Lobby where it takes 3 of each material to craft a Shadow Shields:

1 Star Shield: Zombies Gardna
3 Star Shield: Ghosts Gardna
5 Star Shield: Cursed Gardna

EDIT: Thankyou Skye-Lightning for the names.

All these shields have Curse + Stun Resistance + Shock Penalty

Description: A possessed shield which contains the Soul of Stallos.

Level 4/2:

Tortodrones Finale:

So you are on a large platform, and there are 2 Tortodrones on the platform. Infront of the platform, in the distance, you can see a lower platform with a Tortodrone with wires, indicating that that Tortodrone is a template for creating all the others. Note that these Tortodrones deal elemental damage, however they are neutral to every type of damage. Stallos made this because he knew that his army was weak to elemental (and piercing for the Trojans).

So there you are, on the platform. Stallos in his lair can see everything, there are 2 large screens on each side of the room. He stops duplicating Tortodrones and focuses on killing you. He picks up 2 Tortodrones at a time and lowers them onto your platform. He also gives the template as shield like this (http://wiki.spiralknights.com/File:Monster-Battlepod.png) and you must kill the Tortodrones. These Tortodrones were made with a small block of energy which would blow up. Seems like these Tortodrones were self-destructive. You pick these blocks of energy up (like vases) and you need to throw these at the Tortodrone template. Seeing as there are 2 Tortodrones, one of their blocks of energy breaks their shield and the other damages the template. After that, the shield comes up again. You need to throw 5 blocks of energy at the Tortodrone Template (not the shield) to kill it. The template can also shoot mortafires (the rockets that come from above). If you miss with the explosive block, then after a short moment 2 more Tortodrones come down. After damaging the template itself 3 times, it can then pull wires from the ground like in Ghosts in the Machines. Once you destroy the template, because it is connected with wires, it corrupts the entire systems, causing errors, sparks, and explosions to occur, at this point you need to make it back to haven! You must go back onto the Train which is no longer haunted and take it back up to Haven.

T1- Only 1 Tortodrone, much smaller, template doesn't have a shield (Wires appear on your last time to destroy the template)
T2 -Still only 1 Tortodrone, slightly bigger and stronger, template still doesn't have a shield. (Wires appear on your 2nd last time to destroy the template)
T3 - 2 large Tortodrones, template has a shield. (Wires appear on your 2nd last time again)

If you complete this task you receive a mission reward: A Normal + Elemental Handgun (No statuses)

T1 - (2*)
T2 - (3*)
T3 - (5*)

(Note: names would be very much appreciated)

Again, I can't think of any names. The Handguns a one shot gun, where once you shoot, 3 wires come out of the ground. You can still move while the wires come out of the ground. Charge attack: 9 Wires come out of the ground like this: \|/ and they spread. I figured that the WRH and DR are very unique weapons, so why not try and keep the mission reward weps unique?

Any feedback is appreciated. If you think any of this could be improved then please let me know! (I.E names of each level)

Note:

"I'll try not to make this too long otherwise I'll bore people to death."
I think it's too long :P
