A normal locust in Repentance
What changes
The conversion does not grant Tech X laser rings or an electrical special locust in this version.
How to approach the setup
Before using Abyss, compare a normal extra locust with picking up Tech X itself. Leave the pedestal intact until you have chosen which attack you want.
A practical suggestion for this pair. Check the rest of your inventory and the room before relying on it.
The caution to remember
Keeping Abyss and Tech X as held items is different from consuming Tech X. Advice about a special electrical conversion comes from Repentance+ rules.
What this teaches about a run
A familiar item name does not guarantee that conversion preserves the item's weapon. Version checks can prevent an irreversible pickup decision based on the wrong expectation.
