The lockdown items are really nice and i wish i could take them to the clockworks but, for example, in an arena a striker booster would be kinda useless.
What im suggesting is something pretty much like a shadow lair.
To enter this "krogmo path" you would need a krogmo key wich can be bought from sullivan for the price of 400 krogmo coins (we gotta give the item some rarity).
After you got the krogmo key you do the same as you would do if u had a shadow key. Travel to a subtown use the key and enter the krogmo path with your current party wich cannot be changed while in the krogmo path.
When u first enter you will notice the arsenal station and also the stations where you can change your class.
The place would be kind of a palace and, just like in shadow lairs, the monsters would be a special kind. Lets say chromalisk, they can turn invisible but they will also have a radar just like a recon. Other monsters will also vary from their normal versions but i leave that to the developers.
As you reach the end of the krogmo path you will have to face the king krogmo and after the battle you will get a krogmo jewel http://imgur.com/pIGue
it would make no sense to spend krogmo coins to get krogmo coins so thats my solution. The krogmo jewel doesnt have the normal skull token image as the other bosses because i think that king krogmo isnt actually an enemy.
Let me know what u think.
intersting, could be nice, would need to have a time limit as otherwise guardian sheilds healing power would make it far too simple. Would also need a way for monsters to detect cloaded recons, otherwise evryone could go recon and slip by monsters that dont need to be killed to open a gate.
