OK, I made a long thought out reply, and got randomly logged out, and lost everything. Here’s round two.
Fantasy games are perfectly safe. I’ve never played the particular game you speak of, but if it’s anything like most of them, then it’s fine. I have played numerous fantasy games, read fantasy books, and am a fan of Harry Potter. This stuff doesn’t even come close to real life witchcraft. Not even a little bit.
So you know what to actually avoid, I’ll explain a little on the subject. One example of real life magic seen today is divination, that is fortune telling. Tarot cards, palmistry, etc. Avoid these things, some people say not even read your horoscope (it’s also basically just made up randomly, and as it’s commonly done, it has little to do with actual astrology, so take that as you will). The other thing is spells. Spells are basically just a form of prayer for Pagans. The most common religions to use spells are Wiccans/New Age/Pagan (all Wiccans are Pagans, but not all Pagans are witches, so I seperated them). They use spells for what you would expect them to use prayer for. That’s it. Nowhere near as exciting as flying around, casting lightning bolts. They’re just another religion; they don’t get special powers. Also, most of their teachings say not to use magic to hurt others, just as you wouldn’t pray for harm to come to another person. Still, as almost all spells invoke a Pagan deity or some other spirit, it’s in direct violation of the first commandment, so no Catholic should perform them.
It’s basically just another religion; don’t do their rites or pray to their deities, and you’ll be fine. Fantasy book section/video games/movies is not where you will find temptation. It is occult stores/fortune tellers.
