Many people often wonder why this site has so many spells that are obviously fake, and with good reason since this site is meant to be about real magic. The answer to this question is usually along the lines of the spels bringing people or money to the site. While this is indeed a decent answer, I'd like to propose a different point of view. It's one that I've voiced in a couple of other threads, and I'm sure I'm probably not the first to think of it.
Whether or not a spell is real, it can still allow someone to practice the basics to some extent, and usually in a fun way. Here are some examples.
. Spells that claim to allow the caster to create fireballs can teach energy manipulation. The thing to remember here is that this energy won't actually burn anything, at least not physically. The same gos for fake spells that claim to allow someone to summon ice and things like that.
Spells that claim to allow the caster to teleport often instruct one to visualize the desired location. While the caster obviously won't physically go anywhere, this can still help them learn how to sharpen their visualization skills, especially when visualizing a place from memory. This could be useful for astral travel for example, or even real protection spells that need the caster to visualize an area to protect. I'd even go so far as to say spells of this nature might open a path for someone to get somewhere by normal means if such a possibility exists.
A post about fake spells wouldn't be complete without talking about the many transformation spels out there. These claim to allow the caster to transform their physical bodies, which is obviously quite impossible. However, such spells can probably be useful for practicing astral or mental transformation, and even glammers if such things actually work at all.
These are but a few examples of the many fake spells floating around. If nothing else they can encourage imagination, but it's still important to remember that magic has limits and can't do everything.
I'd also encourage people to be careful with certain fake spells even if they may not do exactly what they say they will, particularly when dealing with hexes and curses. While it's highly unlikely that one of these will result in severe injury or death, throwing energy around with ill intent can still be a bad idea. Once a spell like that is released, fake or not, you don't really know what it's going to do or how it'll interact with the energy around it.
