This is a spell i made while messing around, which uses a mechanic in a mod named Solid Mobs. In Solid Mobs, entities that are landed on will take a portion of the fall damage. So, logically, I made spells that rain down decoys on an area! There are two, Phantom Barrage, and Shadowweaver's Pride. The latter, as the name implies, is the one I am more proud of, and although Phantom Barrage probably has less practical usage, I still really like it.
Here are the glyph patterns if you want to try these out yourself!
Phantom Barrage (contained in a mirror for that extra spell slot):
(Dilate Time)⛓️
(Amp 2)
(Amp 3)(Propagate Homing)
Shadowweaver's Pride (contained in a wand for that extra slot):
(Propagate Overhead)(Amp 3)(Amp 3)⛓️(Conjure Terrain)(Propagate Homing)

Phantom Barrage will periodically summon waves of decoys, and hurl them away from you, bombarding an area.
Shadowweaver's Pride will create a ton of decoys, and rain them down below where it was created, dealing massive damage to whoever is unlucky enough to be hit by a falling simulacrum.
BONUS SPELL: Shadowweaver's Stepstool: It boosts you up and spawns a decoy below. Funny, and useful if you need some extra height, or feel like dropping a fake upon your foe below you. Works best if not moving. (NOTE: do NOT stack more than 5, or the devil will claim your soul. AKA you get sent to the void)
Glypths (i personally use mirror, but just casting from a spellbook works too.):
(Propegate Underfoot)
Enjoy!
