# Parma magica hesitation

Helllo

While reading the "Arma magica" part of HOH TL (p. 30 and 31), I read this: "A magus always receives his Form bonus against magical attacks".

Great shock.

I go read the Core book, which says (p 85): "the parma magica, Bonisagus's great invention, is an Ability that grants magic resistance that adds to the resistance arising from a maga's Form scores.
Parma magica adds magic resistance equal to five times the maga's score in the ability to the resistance based on her Forms"

I looked for an example of Parma magica calculation but found not.

Imagine a magus with parma 4 (specilised in Vim), and art of Ignem 12.

Is his Ignem parma equal to:
A) 45 + 12 (form score) = 32 (what i always believed and what my IRL ASG said to our troupe when we started the game.. i find it really easy)
or
B) 4
5+ (rounded up 12/5 = form bonus) 3 = 23 (what the HOH TL read in conjunction with the corebook could want to say...)

Exar, desilusion?

Edit: while rereading, maybe the quote from HOHTL wants to say: "no matter what, the form bonus used when soaking a spell is always taken in account" [and that is something I already knew], but now that I hesitate between A and B solutions, I want your help because this doubt is somewhat killing me

option A

Previous section same page clearly states "...equal to their score in the Form...".
So definitely A.

Thanks.

Sometimes doubt is killing me
