Mac an Luin

is the Noble Phantasm of Fionn mac Cumhaill. It is a magic spear that is said to have defeated the wicked fallen Divine Spirit . A two-handed spear with a length of two meters or so.Fate/Grand Order material III - Fionn mac Cumhaill, p.124-133
A spear which, in addition to having an auto-attack function, can nullify mental disruptions that can work on the Servant. Upon activation, it shoots a stream of water, an element that his ancestor Nuada controls, towards the enemies.
The name originated from Fionn's sword, but it is often seen as the same as his god-slaying spear. Thus, when materialized as a Noble Phantasm, they are morphed together.
