Difficulty of a spell

[Trantor]

We all know that a ZO spell is easier done than an OH IR RA spell. But if I create a completely new spell in RTC, how do I determine how difficult it is for the casting character to perform? I'd like to have a spell that's really hard to cast (not as hard as VI in Conflux, but still harder than the average spell). How can I achieve this?

Well in order to create a completely new spell, you still have to clone one of the old ones. So look at the difficultly level of the current spells listed on the DM encyclopedia site and then clone one that has a difficulty you want. It should use the same difficulty class I think.

Also keep in mind the higher symbols make it more difficult to cast too.

Although if you cloned oh kath ra into a zo spell, I believe it would be a zo spell 4 times harder to cast than before.
