W.R.T. A61
- Eldritch Blast isn't an invocation, so it should be purely mental, right?
- Unless it's printed somewhere else, this is all the info I can find on Magic Insight:
Spoiler: Magic Insight
Least; 2nd
You can use detect magic as the spell (PH 219). While the invocation is active, you can end the effect as a full-round action to determine all the properties of a single touched item (as the identify spell, PH 243, but with no components required).
As I said, it doesn't seem to explicitly have verbal or somatic components, as other invocations do. Would it be purely mental then?
Edit: Dragonfire Adepts also have the line that all invocations have somatic components, meaning dragonfire invocations should fall under the Warlock restriction, too.
I've also spotted the line in Warlock as well, and it also explicitly mentions EB. Sad.
