Doing formulae from skills with experience-limit?

[Stephan-Alexander Heyn]

Dear participants,

during my tests about new formulae I wonder if it is/were possible to limit formulae according to a level/experience-limit.
Did I probably missed the manual?

Background: doing difficult formulae for creating powerful/expensive items shouldn't be that easy, that a level 1 player can do them:
e.g. creating a small ring should be OK, but a ring with some extras (stats, resistances etc.) should be not.

best regards,
