Arcane sigils. Not important writings.It's a little box that contains important writings to the lich. Getting everything correct is not a requirement of appropriation. In fact, it misses that bad appropriation makes such mistakes all the time.
And THIS is where the appropriation is happening. The word is Tefillin. Not phylactery. If you want to fight the appropriation fight, start campaigning to remove the definition in phylactery that refers to anything Jewish. The English speakers have appropriated our word and renamed it.Except that the most commonly-used version is still referencing the Tefillin.
It's not happening in D&D which doesn't use that definition. And as I pointed out, Jews don't use phylactery. They use Tefillin.
