Guild Wars 2

I have 250 Mystical cogs. What do I do with them? Are they useful? Should I just sell them?

Do you also have toy frames from the Wintersday event? You can craft a mini or endless tonics with them in the mystic forge. The other materials were drop of magic glue and wad of enchanted stuffing which were not account bound so can still be found on the TP. I think you best have a look at the wiki pages of this game.

Edit: I found some extra info, you only need them for the toys, not for the endless tonics. They only require the other ingredients (toy frame, glue and wads with some dust).

What is the advantage in creating toys?

There is a song about it.

Do they contribute to my character any other way than just fun?

they contribute to your character by being fun :P

I deleted mine, since you can’t make toys anymore.

By that I mean you can’t buy rest to make a toy. Or am I wrong.

You cannot get more cogs and toy frames, but glue and wads might still be on the TP. You need 250 cogs to create a mini or no cogs to create an endless potion.

Keep them in your bank, you never know, we might get to use them next year
