Greetings, everyone who reads this "something with nothing based on bad knowledge of English".
I got this idea for a long time and actually it's most likely in my head as a part of Core Opening event idea, which I maybe post later(or not, because Core will be sealed FOREVER), but after some thoughs I think it can be stand-alone idea as well.
So here's the point - I guess lot of SK veterans already did Shadow Lair at least once. Lots of peoples may think it's good, or maybe bad - there's lot of points that can be hard, laggy, buggy and such. But I guess everyone can say - Unknown Passage is most amazing thing in any SL run. At least for me. And actually... for me it's the main reason why I wanna investigate SL again and again, catching every chance to run in this dark place.
Point of the event - in some moment, Clockworks depths out of Shadow Lair been investigated with Void levels. Like it's been in SK Birthday event, we can have random arenas with Void monsters... or even better - "no-energy-pay" elevators on Unknown level there you gonna go through army of Void monsters with main point to survive, as it is in usual Unknown Passage. At the end - something unusual(some event tokens or rare material) thing and elevator on next Clockwork level.
Also - prestige mission, there knights must investigate Swarm zone that showed up just in the middle of the level you need to go through. This level can be combined with both usual and Void monsters, have random theme(gremlins, beasts etc.) and random reward.
If there's gonna be tokens - it can be pretty much good idea to sell shadow accessories for those(which is, in some point, can make them cheaper and bit less rare as they're right now). If materials - you can make some new weapons or furniture, which is also can be pretty good. Event-related stuff is always looks good(I like scarves and mewkat masks, lol) and pretty much welcome, I guess.
But - there's must be some things that don't let everything take a part in event. As long as we talk about Void and SL, I guess that Unknown levels/arenas must start to show up not earlier but after Tier 2 Terminal, to most likely lock the access to everyone who has equipment weaker than 3*. It's pretty logical in my opinion - Void is pretty danger, so there's no way that new players with 0*-2* can investigate what is actually would be in depths of Shadow Lair. Same with mission - it must be avaliable only to knights who have access to danger missions, and should give good amount of prestige with limit 1 mission per day.
It can be good to make event 1 or 2 weeks long, and not connect it to some date, like "it's gonna happer every year in current date". Also, after full-leght event it can be nice as well to randomly put Void levels in Clockworks on 2-3 days in random days. I guess it can be pretty fun.
Feel free to comment and ask questions if something is hardly understandable. I'll do my best in explaining the things I hold in my mind. As long as I feel it a good idea to realise(and I gonna feel upset if I never gonna see at least a thread about idea of such event).
Cool idea!
