I now have a chance to purchase a Sword of the Paruns on a westmarch server I play on and it was brought to my attention that I should be able to give myself the reaction attack. Seeing as I'm a paladin without pam or a multiclass for defensive spells, this seems incredibly good. So, does this work?

Can I give myself reaction attacks with the Sword of Paruns?

It doesn't say "another creature" or "a different creature". It just says a creature within 60 ft of you and if that wording works for spells, as was clarified by sage advice, then it'll work for you. You are a creature within 60 ft. React away.

Yeah, sword of the paruns should let you use your own reaction. Pretty good, I don't think I've ever seen a reaction dash before, going to have to remember that for maximum movement builds.

Sick. Thanks! 4 attacks per round here I come.

 Attack, extra attack, reaction attack = 3.

You going to take dual wielder feat for the 4th?
