A slower poisonous locust
What changes
The Repentance locust does not supply Ipecac's explosive tear weapon or its flat damage boost to Isaac.
How to approach the setup
Compare taking Ipecac with converting its pedestal before using Abyss. Keep your existing weapon if that suits the run, and aim the added locust through an enemy lane.
A practical suggestion for this pair. Check the rest of your inventory and the room before relying on it.
The caution to remember
The Repentance locust is not an exploding Ipecac projectile. Taking Ipecac instead changes Isaac's damage and weapon, so the two choices can affect the rest of a locust build differently.
What this teaches about a run
Conversion trades the item's ordinary effect for one helper. Evaluate that trade across the build rather than by the helper's color.
