Greetings, XYZ!

The crafting system works as follows: if your Hero's level is below required you can't wear the item, but it still appears in your stock.

As it appears that lots of questions do not appear to be answered by anyone on the forum,I wasn't that hopeful, so I wasn't expecting such a fast response at all, let alone Ivar Marksman himself, the administrator.

Thanks for your answer.

I suppose it is largely unimportant now, but what you described is not what happened to me,so you might see how I had difficulty in understanding how Bjorn, in the recent  puzzle  competition was able to make, 

Harald's  Tooth, Eric's Horn, Olaf's Armour and Siguard's Cloak, let alone then use them to then make Brodin's  Flail, especially as  the text in the game reads , and thus suggests

in order to make any of these you have to be level 50 hero.

We're glad that our contest aroused interest in you.
