User-created prerequisites to official Charms???

[Solfi]

... Are user-created Charms really allowed to be prerequisites to official WW Charms? After all, bringing in more Charm prerequisites will effectively raise the cost of getting said Charm. And the official ones are supposed to be balanced already.


I'm thinking of this official Charm, which has this Charm by memesis listed as it's prerequisite.

For canonical Charms, you should treat prerequisites as guidelines only, and look at the source material for the "real" prereqs.  The prerequisite system we have now is an either-or proposition (Charm A depends on Charm B or it does not), with no room for "alternate prerequisites" - and you will find many Charms which explicitly say they can alternately be prerequisites for some other Charm.  That mine does not is a failure of the Charm text, and I'll go update it - it was originally ported from the Exalted Wiki, where it does say that.
