I don't know much about illusions, but how can they be seen by others far, far away?

It's a bug. It's not supposed to be seen.

I think in this case it was a pre-programmed illusion in the room, rather than a bug. I've seen others that were bugs, however, and appeared as purple with the plants in a room, even on a squint. I don't think anyone is capable of THAT maneuver, or are they?

Programmed only fires when you enter the room, and improved can't have a delay of more than 250 seconds.

Still doesn't answer how I had an illusion in my stockroom when I arrived in the realm...

Plus, the vitae illusion also hit my coven which was sitting safely in Serenwilde while the fighting was going on elsewhere. I highly doubt anyone would have crept into the forest just to play a prank like that. It certainly is buggy.

Both of these were posted when I went around and programming illusions.

Can you program illusions in rooms you aren't standing in?

No. I think its just a programming bug, or else that Vernal God (I think its Tzarikio) makes any illusion duplicate all over the place - which would be a cool feature.

This one came up randomly while I was fighting an abhorrence. Found it amusing, I assume it was Silvanus' work.

Both heads down, a two-headed abhorrence charges into you, knocking you to the ground.

But see, that didn't go off when I entered the room. I had been going at it with that abhorrence for a while and it randomly popped up.

Vestera, I think you're thinking of.

But can you get in trouble for illusioning fake prompts like one that went
