Swarming, biting locusts fill a 20-foot-radius sphere centered on a point you choose within range. The sphere spreads around corners. The sphere remains for the duration, and its area is lightly obscured. The sphere's area is difficult terrain.
When the area appears, each creature in it must make a Constitution saving throw. A creature takes 4d10 piercing damage on a failed save, or half as much damage on a successful one. A creature must also make this saving throw when it enters the spell's area for the first time on a turn or ends its turn there.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th.

Thinking about the time in The Adventure Zone when Merle decided that best course of action for sneaking past a large window was to cast this spell and block the view with bugs
I think repelling blast only applies to eldritch blast by Raw (but if you have a DM who is willing to bend [homebrew away] some rules, you could also it applies to whatever other spells you have that deal force damage such as Magic Missile/Disintegrate)
No I meant using repelling blast to knock enemies back into the insect plague
What a staggeringly terrible spell compared to similar spells of the same level like Synaptic Static, Cone of Cold, Negative Energy Flood, or just upcasting your Fireball.
- 5th level slot for a measly 4d10 damage (average damage .
- Uses the most commonly high saving throw
- Can't be moved despite being a mass of living creatures.
- Concentration monopolized.
It has its niche uses I suppose, but 9/10 you're better off using Cloud Kill if keeping enemies inside the area isn't going to be an issue. About the only thing this spell has going for it over something similar of the same level like Cloud Kill is that the damage goes off upon entering, not ending your turn inside (which would have made it pointless for anything less than a 30 foot radius).
I cast animal shape on all those locusts
I know the meme you're talking about and it doesn't work; from the spell description:
A swarm of locusts are not necessarily willing, so this would be up to the DM's discretion. Like a trained dog might be considered willing, but a swarm of wild animals? Naaah.
You also have to consider whether each individual locust is considered a creature (a specific definition in the PHB), or whether the entire swarm is considered one creature (per other creatures in the MM ala Swarm of Rats) or just an area of affect spell, given there's no way for a character or NPC to target the swarm with an attack. Given the second line of the spell specifically states:
I'd be inclined to rule that it is the latter, and whilst a funny abuse of the rules, it's neither RAW nor RAI.
