New erratum for character sheet?

The 3rd page of the character sheet (even the revised version) has this formula:

Multiple Casting
Int + Finesse + stress die - No. of spells, VS 9

What does this refer to at all? The aiming roll uses perception, and is compared to a variable defense total... Am I missing a rule with this roll when attempting a multicast?

Nope, it's a legacy line that should've been removed.
Has been discussed before.
It refers to multi-casting rules under an earlier edition.
Have a nice day. :slight_smile:

Thanks.... if it's well known, should it not be included in the official errata, or even better in a 3rd version of the .PDF character sheet?
