Yeah, I flatly disagree. The spell manipulates your perceptions with illusory sensations and false peception.
If you've been drunk or had a hypnic jerk, you've had your perceptions messed up well enough to feel like you're falling or like the world is unstable. Hallucinogens like LSD can cause even more extreme false perceptions. Optical illusions trick you into perceiving depth all the time. Strictly speaking, making an object look like there's something coming out of it and
making something look like it
has a hole in it are identical tasks as far as manipulating the eyes are concerned. The distinction you're drawing is completely arbitrary here.
I agree that this doesn't work for spells like Minor Illusion and Silent Image, because these spells are just manipulating the reality with light effects, etc.
But Phantasmal Force is different to that. It takes place in the creatures mind, so almost everything is possible. I find that Bacon Bits' examples are quite reasonable.
You need to CREATE an object, not remove one. You are creating the illusion of an image. That is fine. The creature would go "oh wow what a nice image, it seems like there's a pit here". You do not automatically trip it with peyote, nor make it believe that the image of the image is something different than an image. You can create a PIT, and not just the IMAGE of a pit, it just has to stand in a place where there's nothing else to interact with that would make the illusion unworkable. It does matter where the illusion takes place, if there's no space for the illusion to be, then it's not possible for the creature to be affected since the illusion is not visible.
You create the illusion of a bear? There's a bear, for that person.
You create the illusion of a sword? There's a sword, for that person.
You create the illusion of a pit under the feets of the person? The floor is still there. You cannot delete the floor.
You create the illusion of the image of a pit? There's an image of a pit, for that person.
A cage? Fine. A cage with sharp knifes on the top? Ok. A cage with snakes? No, objects and creatures. That half that wall is invisible? Nope, can't delete reality. Spectral chains coming from a space rift? It's cool, go ahead for me. A house on fire? very small one, but yes. Fire on that house? Yep. Fire on that house that's also now half destroyed? Nope. A door in the wall? Good. A doorway? No. The image of a doorway? Yes, with all the limitations of such an illusion.
This spell does not let a person go Wile-e-Coyote and Roadrunner. It lets you create an illusionary object, creature or visible effect in the mind of a target, and that's it. If you want, you could make its sight go trippy.But it doesn't make a person intake LSD. Unless you create the illusion of LSD and the person really wants to try it.
[MENTION=77538]Undrhil[/MENTION]l I think you can actually make it real, and once its real it's real. But do not quote me on the "you can" part.
Now i want to play an illusionist that Phantasmal Forces himself to see LSD and makes it real...
