Not according to p. 11

Strengthen Arcanum: Give +2* to cancel a spell

Edit: Repair Undead heals 3d damage even though the text on p. 13 says you can't heal more than 2d.
Edit 2: Could you halve the cost for Radiant Shield by bestowing a +2 bonus to Active Defenses instead of +2 Defensive Bonus? Does DB do anything else?

That's different from girded a spell. For girding an existing spell, yes. For the spell you're casting you may simply add it "free" - much like Duration or Ranged. Giving yourself a bonus to cancel a spell is pretty much for dispelling.

That's errata.

I suppose. But the nature of the spell would be changed.

Ok, thanks. I'm loking through the grimoire now, so that''s why tre are so many questions. :)

hello,

i'm trying to build my spellbook and i had a question about "shield" spell
I wanted to create a basic single-target shield spell with DB+3 and to me it was a bonus to active defenses with a 20 cost. The idea was to boost my parry with it obviously, or boost someone's dodge or block or anything like that. No actual blocking with the spell, quite like the shield spell from the basic set.

However, on Radiant Shield, the cost is 60 and includes altered trait.
How does this work and why ?

thanks in advance

Edit : or maybe it is because SB gives a bonus to 3 active defenses, thus +60 and not +20 ? (i think that's the reason why)

My player found one problem with Incantations mechanics while reading the book.

The problem is that the caster can prepare a complex ritual, which for example will be cast at 6 (because of modifiers), and even if he fails it, he still attaches it, even if in a normal situation he would not have been able to create it.
He can then cast that ritual with only a -3 modifier instead of say -10. And that looks like a bug.

Was it intended that way, and if not, how can it be fixed?

Yes, it attaches, then you roll at your skill at -3. If your skill is a 6 and you have to roll for the spell it's a 3 or less meaning your critically fail on 13 or more. That's...not great.

You can absolutely raise the penalty higher, I originally used -5 but the playtesters thought that was too harsh.
