So we shouldn't have fantasy religions with adherents who keep relics in a reliquary? No saints? Can a Cleric be described as wearing a stole, habit or some other vestment?
I don't know if I've ever witnessed the word phylactery used outside the context of D&D. I don't have much skin in this game, I don't really care that WotC and others decided not to use phylactery, but I wish they would have picked something besides spirit jar. I'll continue using the word phylactery in my games though because I honestly don't think anyone is offended by it.
