Bonus to spells?

[Bullwinkle]

Can somebody explain how exactly the property 'bonus to spells' works? I thought it added to the roll needed to succeed at casting a spell, but unless I'm missing something, it's not working that way.

 

I'm trying to cast the Revision of Skills spell (Intelligence/Revision v. 12). I have a Revision skill of 8 and an Intelligence of 3. Before I cast the spell, I cast Wand Amplification (+4 bonus to spells). This means I should get a roll of at least 1+8+4=13>12 and so a guaranteed pass. Yet I still occasionally fail to cast the spell.

What you have said is correct. I'll examine Bonuses, but it's possible for you to still fail due to hidden factors.

 

Thanks!

Fair enough, although if that's the case, it's a pretty big penalty. After I cast Wand Amplification, I cast Wizard's Aid, and then Revision of Spells, which should give me an unadjusted minimum of 15. Yet I still failed. So the penalty is at least -4.

Looking into the Roll, I don't see anything that leaps out at me. We'll test the Bonus provided by Wand Amplification.

 

Thanks!
