My players are creating Treasures and we have a question.

If you roll to activate the item, either Glamour or Int. + Gremayre is the difficulty: 8?

That seems fairly hefty since you can't do a bunk?

I'm considering lowering the difficulty to 6...

or

Reducing the difficulty by the rating of the treasure...

From the perspective of people not knee deep in city creation will either of these work?

Thanks
