Let's see.
How about ... Smites?
Auras?
Sacred Oaths?
I feel like there is some commonality between these things I dislike, something on the tip of my tongue ...
They're all favorite spells of gnomes? Hmm ... not quite...
Any of the conjure 112 pixie, squirrel, mephit, or manes spells (I am exaggerating the number, it only feels that high). I think it would have been more elegant to give them a swarm and have the size of the swarm increase with the level of spell cast (or summon a what amounts to a wall of angry mephitis/sprites/manes, and since the wall is pretty short, the party can range attack over it).
