So I wanted to ask, as Im currently playing a 4th level Unchained Monk and right now im running through the campaign of Return of the Runelords and we have gotten to level 4 so far. Were using milestone so level 5 is close. And within the progress of the campaign, my monk has the rapier and gauntlet artifact. On top of, ive been roleplaying as a worshiper of Cayden Cailean, of which his favored weapon is a rapier. So this is to perfect for me not to give up. But im wanting to use this rapier artifact to its fullest potential. While the magic effect gives me proficiency with it, it is not a monk weapon and I can't use furry of blows with it.

Which is my main issue, so after doing some digging around trying to find something to make this work. I found Crusaders Flurry, but I need channel energy as a prerequisite. So I was thinking that I multiclass into cleric: crusader to get the free Weapon's Focus feat along with channel energy. But beyond taking 1 level in cleric. Im not sure if it be fully worth it. And as such, I wanted to ask the community how would they go forward on this? Im really wanting to use this rapier artifact as my unchained monk but im not sure how to exactly do so. So any help is appreciated on how to build a cleric unchained monk multiclass, or should I just drop it the artifact for someone else in the party as a Unchained Monk isn't the best to use this even with multiclassing?
