"You may roll dice equal to your Craft value. For any doubles you get, draw 1 Spell and then discard down to your Spell limit. The Riddle Stone then crumbles away to the discard pile. If you get no doubles, then discard all of your Spells and the Riddle Stone stays on this space."

I have 6 craft Value. I roll 6 dice:

1,1,1,1,2,2

How many spells I draw?

2,3,4,6? Why?

3 once a double of dice is resolved no more of the die can be linked again to another double so 3. Stands to reason.

3 once a double of dice is resolved none of the die can be linked again to another double so 3

I don't understand what do you mean.

Do you mean this...

1-1 first spell

1-1 second spell

2-2 third spell

Or do you mean this...

1-

1-1-1 = 3 spell

-2-2 = irrilevant

1-1 first spell

1-1 second spell

2-2 third spell
