I've heard from various people that it is odd that I write my spells in other languages( mainly Spanish, French, and Greek), and they've told me that it weakens the power of it. However, I believe that it gives the spell more power and makes it more personal to me. I am of Spanish descent, speak near fluent French, and my patron gods and goddesses are all Greek. What do you think about it. Does it make it weaker, stronger, or does it have no effect.
