I remember reading once Fionn having a spear that never missed.

I did once a Lancer Fionn (it was in his prime, still fair haired, young and idealistic, unlike the old and bitter Fionn in The Pursuit of Diarmuid and Gráinne) and I gave him three NPs, a spear, a shield and the knowledge. The spear never missed because it had the ability to create wormholes, so it could attack from any direction within its range. I thought that as Nasu totally made up the Gae Bolg ability to reverse causality, I could give it something similar.

The shield had a wind barrier similar to Invisible Air (to draw a parallelism between Arthur and Fionn, given that both share the "king under the mountain" heroic motif) that could be used as Strike Air and sealed Balor's powerful venom as the folklore says.

The knowledge was mostly like in the myth, but it was a bit nerfed and limited as it was for a tabletop roleplaying game campaign.
