Anti-air Spells?

[NineHostages]

I'm designing a magic weapon with the intended purpose of bringing down any monster with a natural fly speed, for a short time. I've been sifting through the books to find a suitable spell or magic weapon property that fits the bill, but I can't seem to find one (and that's ok, I just want to know if there's a model I can use).

To be more specific, I'm thinking this is a boomerang which can, on a successful hit, and with a failed save, reduce a creature's fly speed to 0, and bring them crashing down to earth. The effect should only last a few rounds, or just one.

Reverse Gravity? It's certainly powerful enough (if not more).

this screams legend of zelda to me for some reason.

That is quite a spell, but I believe it says flying creatures can maintain their position.

Hold Monster.

Thank you LazarX, that is an elegant solution. I'm looking to make this more low-powered, so I don't think it will actually paralyze the target, just make them fall. I will share when I calculate cost and crafting stuff.

The spell doesn't have to precisely match the item, just make people nod and go "I can see where that's coming from". And multiple/high level spells make it harder to make the item without being an advanced caster.

Hold Monster seems pretty good to me.

I immediately thought of this. You could easily create a spell that does this. Fly is a 3rd-level spell, so that might be a good spell level for it. You could then apply the spell to a magical boomerang. The item creation rules would be useful in determining the appropriate cost of such a weapon.

I promised I would share this, the Gullslayer!

This +1 returning boomerang is carved from a rare hard wood, which is black and resinous. It’s surface is decorated with stylized images of human hunters dancing over a fallen bird. If thrown at a target with a natural fly speed, the boomerang has the additional effect of removing the target’s ability to fly, if it fails a Fortitude save (DC 20). With a loud crack of thunder and a dramatic burst of light, gravity will claim the offender. The struck target immediately plummets to the ground, and will be dealt falling damage based on it’s height. The subject’s fly speed is reduced to 0 for 1d4 rounds, but is otherwise unaffected and can still act normally on the ground.
