I was thinking to suggest a few ideas :
1 - Giving it a range instead of forcing a squishy mage to walk all the way to his target.
2 - Making it an instant cast (it is supposed to be a single word, after all) - like a free action? or a quickened spell? something in that direction.
3 - Giving it some save based side effect? Can't say I got any bright ideas on that one.
Why I think such could be a nice addition? well, this line of spells is practically useless (at least in my time playing a DC wizard), the only time I saw a good use of it was by the Pit fiend in the iron mines - and that makes it a sort of gish trick - which tbh, got better tricks than that.
And I know there is Anthilar's bane, But there are far better things to do if you're going to invest two rounds of casting two high tier spells (what you need to cast Anthilar's bane, and then a power word), and in most cases two rounds wont be enough anyways (low hp types tend to have high will save so Anthilar's wont work, low will got high hp so even with Anthilar's it won't work as it is).
Main aim I got in mind is to have a more diverse range of DC mages (which are scarce in general, Necro being the usually preferred type - for obvious reasons), and I would also personally like to make diviners more fun for selfish reasons

What do you think?
