From that conversation:
[09:27:14] zanzarino: Shard of passion looks very similar to my first idea for the fire shard that i shared in chat a long time ago
[09:27:50] zanzarino: But I did a bit of math and the mechanic is easily broken with a firestall
[09:28:32] Kuroaitou: ‹@Xenocidius› So... it's not inspired?
[09:29:25] zanzarino: No, I would say not inspired
So even if it had some unconscious impact on Zanz, he doesn't remember it.
