Magus Spell Combat
 

How do I know if the -2 attack bonus from Spell Combat is shown in my weapons total attack bonus? Power Attack has a toggle/activate button, does Spell Combat have one that I’m not seeing?

To the best of my knowledge there is no toggle and the -2 is not added in.

Someone toss us a bug report about this, if you could please. This seems like a case of something missing that should be present.

A toggle button would be nice.
It is essentially Two-Weapon Fighting, which is already coded.

In general, Hero Lab doesn't display modifiers that sometimes apply and sometimes do not.
Like Power Attack, if you're using Spell Strike, then all of your attacks for the round are modified... so a toggle could show this, rather than having the user remember a -2 modifier to attacks.
