Talk:False Origin (5e Subclass)

If I may ask, What's a good example of this: "When you cast a spell you have learnt using this feature, you choose the direction, target, and range (if any) and use your spellcasting modifier, ability scores, and an appropriate spell slot; otherwise, you cast it in the exact same way as the creature that cast it originally, replicating the appearance and effect(s) they used." I'm unclear on how that is different from just casting the spell. Is there a spell you could use as an example for the "cast in the exact same way"?
