Willow nears the end of her spell. The energy building, things still going floaty. She takes a photo of Oz from her pile of ingredients.
WILLOW
Let this image seal his fate, not to
love - but only hate...
But as she moves to add his picture to the fire, she makes the mistake of really looking at it. She stops, stricken. Then tries again to cast it into the flame - but it's too late. She can't go through with it. She starts to cry all over again. The spell is broken... The bad mojo drains from the room and the floaty objects fall to the ground
It was to make Oz hate Varuica
I know she also talked about the spell later in that season but cant quite remeber what she said about it.

Found it Something Blue...
WILLOW: I am a bad witch.
BUFFY: No, you're a good witch!
WILLOW: I'm not kidding anyone. If I had any real power I could've made Oz stay
with me.
BUFFY: Yeah, but you don't want him to stay because you -
WILLOW: I didn't have the guts to do a spell on Veruca, my "I will it so" spell went
nowhere, the only real witch in here is fuzzy little Amy!
