It would be pretty cool to mess around together to solve puzzles and kill baddies to clear an area

Every season has its own co op dungeon so you could change it up a little every season to keep it fresh  

To be honest, Kinda a fun idea really. Never thought of it. The thought of working with others or alone to solve a dungeon puzzle and kill baddies sounds fun, I actually could see myself wanting to do these often. But a few things I'd ask about is

1) What would be the reward for solving these puzzles?
2) How would it be implemented? Like what would be the dungeon team size, Dungeon location? How would teams be placed, Could I create a custom area where u could do it solo or bring only certain people?

I think this would be a pretty nice idea to add to the game. I could see a lot coming out of this really in what it could offer, And I guess out of everything now would be the best time to have it. Since there is barely anything to do on graal anymore.  

Yes.

You could stock up on different variations of the gauntlet over time and have a weekly or daily rotation of the objective. Even just 5-10 levels without dying would be challenging.  

Seems great!  

Like a dungeon that has like 30-60 minutes of gameplay would be fun with a guild or with some friends.

It would be cool if it was daily or weekly. It is were weekly there should be like more "$$$"  

You could steal a lot of puzzle ideas from Lufia 2: Rise of the sinstrals (snes), and Brainlord (snes)

Sprinkle in a few of those purple loot chests and I think we got something everyone could enjoy

For the combat against baddies you could add a healing potion that players could throw at each other (like that love potion, but for healing) and maybe add a survival element (if you die you gotta wait till the next day)  

Since this thread got bumped. Why not add the following

1. Baddy elimination. You have to kill as many bandits as you can before you're eventually killed. No healing. And there is no time limit.  

Yes, this is a great idea!
