Yes, that would be an incredibly good thing to do.
Sorry.
Ok, this is interesting and I don't recall it being talked about previously (then again, this is the fifty-fifth thread and I haven't participated in even half of them). As we all know, http://dragonage.wikia.com/wiki/Spell_Combinations. What I'm curious about is which of these, if any, do you rely on tactically when fighting? Which do you think are the most useful? If you don't rely on any of them while fighting, do you still achieve the combinations intentionally when you get the chance, or are you playing without even thinking about them and just find them to be a nice coincidence when they actually happen?
Personally, I find the shockwave to be the most useful one, because not only does it dispel the awful crushing prison but it also knocks down nearby enemies. It's quite a useful trick to keep in mind.
