Hi there!
I'm finnaly sugessting something unique,that'll make many Knights happy if it ever gets relased.People're sugessting mission ideas,and instead of that,with this update everyone'll be able to create his own missions.They should be findable in a special tab where're the all missions,it should be called "My Missions",and after the Expansion tab.To create a Mission,there must be the props that're already used,every prop,even the Winterfest present spawner,etc.In the Mission Creating mode,there should be a "Props" tab in a corner.There'll be many cathegories in that "Props" tab,for example: Buttons / Switches.Once you click at any prop in the cathegories,it'll spawn in your hands as in the Guild Design mode.But before placing a prop,you should expand your ground,themes can be choosed,and the Tier of a Mission.Also,the Depth number will be choseable,NPC knights that you can talk to (their text will be editable),name of the misison,and of a depth,etc.But map can be ??? or a normal map that you can look at.I think you already got annoyed while reading this.Now,there should be a "Power" system.For example,right click a gate or something,click its Power Cable,and plug it in a Switch.Details're coming now!

START WITH CREATING:
-After clicking the "My Missions" tab,first you create an empty slot,for example: Rank 1-1 The Dark Moon's Curse,and the whole Rank (1-1).
-In the Creating Mode,you'll first spawn on a small ground.You can choose between themes (example.Blast Furance),or a vegetation (example.Grass).
-Then,click the "Expand" button in another corner,choose your theme,then with a big marked cubes (like while placing props at Guild Design) click to use.
-Click in the "Props" in another corner,then place some props.For example,button,gate,5 Gremlins,golden keys,etc.
-After that,get to the "Powering" button in another corner,then click a prop (that can be used after an action,maybe button),use a Power Cable. ^ABOVE^
-Backgrounds can be like Water only,Clockworks,Lava only.
-Test your Mission,don't forget the basic stuff!
-When you're done with that,Publish your mission,3 ways to do it: Publish,everyone. Publish,friends. Publish,guild (if got one).

MISSION SPECIAL GAMEPLAY:
-If your mission looks bored and classic,then make some unique things,like following ones.
-Timed arena.
-Explosion escape.
-Chasing.
-Dodging.
-Special effects+musics!

MISSION RE-DESIGN,DESIGN+MUSIC MIX:
-Find a prop,double click it fast then you'll get to a Re-Design Mode that'll be opened in another tab.
-You can change colours,causes-for example: Causing shock instead stun,pink colour,remove some things.
-Would be harder to design your own props,but still,I hope there's a way to do it.
-Music prop can be found in the "Props" tab.Music's got some effects,like violin,piano,guitar,drums,etc.
-To make a diffrent music in battle arenas or boss battles,use the "Power" system!

MISSION ELEVATORS,CUTSCENES:
-Elevators have got many types,that can be also chosen in the "Power" mode.Switch to themes,for example: Core,Haven,Bazaar,etc.
-Broken Elevators can be there,and (MY IDEA,NO COPYING IF THIS EVER GETS RELASED),the Broken Elevator will bring to my final mission. (MAYBE)
-Cutscene prop should have 2 minicuts that're related.You can place them anywhere,and use the Power system to activate them.

I hope you enjoyed reading this,and liked this idea.
I hope it'll one day become true.
I'm very skilled in building,I'm creative and I really love creating.
I got really awesome ideas already,I think about that every day.
(There must be a limit for placing crowns on the ground,and boxes,thanks to Frozenskull!)
(If's the Mission got 5 or more depths,if allowed,very hard depths,long,and extreme boss battle,max.10,000 Crowns,10 Red Loot Boxes,10 Green Lot Boxes TOTALY)

Thanks for reading (relasing this)!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
