You transform up to ten centipedes, three spiders, five wasps, or one scorpion within range into giant versions of their natural forms for the duration. A centipede becomes a giant centipede, a spider becomes a giant spider, a wasp becomes a giant wasp, and a scorpion becomes a giant scorpion.
Each creature obeys your verbal commands, and in combat, they act on your turn each round. The DM has the statistics for these creatures and resolves their actions and movement.
A creature remains in its giant size for the duration, until it drops to 0 hit points, or until you use an action to dismiss the effect on it.
The DM might allow you to choose different targets. For example, if you transform a bee, its giant version might have the same statistics as a giant wasp.
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.
