HI.
I have been always thinking, what will I do when I finish the shadow lairs ,missions,acheivments ,prestige......I really like the game and I want it longer so I have been thinking of these ideas wich I think will make the game better.
Each idea is divided into : 1- what is it -- 2- game background -- 3-notes.

Idea 1 : 1-add tier 4,5,6,7 .................basicly this tiers will be after opining the core ,it will be at the other side of cradle so as the first half of the planet wich is in total 30 depths, the other half will be divided as : depth 31,32,33,34( terminal),35,36 and 37 are after the core and they are tier 4, tier 5 is from depth 38( town like mooncraft manor and emberlight ) to depth 48( another town before tier6) and depth 43 is a terminal,and depths 49,50,51,52,53,54( terminal ),55,56,57,58 and 59(tier6) and tier 7 is only one depth and its the other side of the world.

2- background : 1-(if the spiral knights want to go back to their home ) Finally the spiral HQ is able to enter the core and found that the gremlins toke alot of energy from the core and they store it in their main city ( tier7 ) wich is called HELL XD,so they have to restore the power from the gremlins to go home.
2-(if the spiral knights decided to stay in cradle )Finally the spiral HQ entered the core and they discoverd that the gremlins live in the other side of the city, and they still want to attack haven,so the spiral HQ has to put an end to this.

3- Notes : 1-depths could be named nigativly starting from depth 31 ....Example : depth 31 will be -29 and 32 will be -28 .....etc
2- Name of the gremlin city could be changed.( But Hell is the oppisite of Haven xD )

Idea 2 : some new weapons : since there will be tier 4,5,6 and 7 .....a 6* and 7* version will be out from each weapon, and the 6* one will be called powerd + weapon basic name .....Example : after divine avenger there will be powerd avenger, livithian blade will be powerd blade ....etc
and the 7* version will be called " Cored + the basic name of the weapon ...Example : blitz needle will be called cored needle and the plague needle will be called cored toxic needle or cored plague needle.
and a new totaly weapons like :" Phantom sword " wich is the sword that the tier 2 phantom has.
2* bone sword
3* cursed bone sword
4* phantom sword
5* cursed phantom sword
6* powerd phantom sword
7* cored phantom sword
abilities of the phantom sword : can deal or cause curse to the player or the enemy like "Faust" ,3 combos and shadow and normal damage.
Shape : Purple Cutter. ( The sword that the tier 2 phantom has)
Charge : 2* shoots a bullet like gun puppy but with purple color.
3* same as 2* but with 2 bullets.
4* same as 2* but with 3 bullets.
5* same as 2* but with 5 bullets.
6* same as 5* but also shoots a fast purple skull head that has a great chance of cursing.
7* same as 6*.
and " Alemrian spear " wich is the weapon that the almirian crusader has.
5* ( earned by 40 almirian seal ) almirian spear.
6* Powered almirian spear.
7* cored almirian.
abilities of the almirian spear : 3 hit combo like the flourish but reversed ( like the way that the almirian crusader does it ).
Shape : Almirian crusader`s weapon.
Charge :
5* charges as the deadnaught .( keeps runing for a while damaging anyone infront of the player and ends with final hit wich will be causing alot of damage.
6* same as 5* but makes 1 explosion after the final hit like brandish sieries.
7* same as 6* but 3 explosions.

2- Background : After the core is opened ,Spiral HQ can upgrade its weapons from the core`s energy .
3- Notes :1- the shapes of the weapons will be changed.( I dont have idea for all weapons now).
2- as the 5* weapons damage bar is full ,then the 6* and 7* weapons may have more than 2 bars.....Example : as the final flourish bar is full,the 6* version ( powered flourish ) will have 2 bars , the first one is full and the seconed bar will is like quarter only filled .
3- tier 4 normal weapons is 5*,but it will be harder than tier 3,while tier 5 is 6* and tier 6 and 7 is 7*.

Idea 3 : bosses ,levels and lab.
New boss : Cursed Phantom : Normal phantom but we will fight it in the gravyard and it has 3 stages.
stage 1 : fights as a normal tier 3 phantom (but with the phantom sword ).gets to stage 2 after some damage.
stage 2 : after he gets to stage 2 he turns into the purple small ball that come out of any phantom when its killed ,and takes a speed tun around the gravyard reviving Carnavons from the ground .
stage 3 : after he gets to it ,he does same as stage 2 but he becomes more stronger and he revives phantoms as will.
This boss can curse and its in tier 6.
OOO should make more bosses for tier 4 and 5.
New level : Gloaming wild woods : it will be like the original one but it could apear in arcade randomly like some other levels.....Like : lichens lair.
And the boss snarbolax could apear at any time in this level and he will be trieng to stun the knights ( It will apear in random places ) , and players could throw a material that attracts him,each time you hit him his token apear,when he gets hit 3 times he wont apear again in this depth again unless you played the depth again.
Lab : as the spirits will be a part from the lab , the lab also may contain :
1- a machine that converts minerals to shards .
2- a machine like training hall but you put minerals in it and it gets you to a virtual training level ( monsters and level theme will be made according to the type minerals and the tier will be according to the knight`s tier and there wont be crowns or heat or mats in the level ), But not that only ,there will be a timing for these levels and if the knight finished the level in a good time he wil get lab tokens !
Example : tier 1 : gold : 2 tokens --silver : 1 token.
tier 2 : gold : 3 tokens -- silver : 2 tokens -- bronze : 1 token.
tier 3 : gold : 4 tokens -- silver : 3 tokens -- bronze : 1 token.
tier 4 : gold : 5 tokens -- silver : 3 tokens -- bronze : 2 tokens
tier 5 : gold : 6 tokens -- silver : 4 tokens -- bronze : 2 tokens
tier 6 and 7 are the same as tier 5.
Lab tokens will enable knights to buy special materials to feed their spirits or even buy a spirit !!

Idea 4 : I hope some monsters back like the "Vog cub" and the sloom.
and a new monster wich is "skolver" (like vog cub but white and shiny with light aura ).

Thats the end of my ideas ,I dont know if someone else suggested one of these ideas, and I hope to see them in game .
Sorry for the bad english. :)
