Remove Fulminant Prism from ghosts

[Midn8]

It will only be encountered fairly early on, and leads to 1 or 2 scenarios:

1. You can't get out of it and it hits you for 30-40+ damage (undodgeable)
2. The ghost nukes themselves and gives you a bunch of free xp

I feel neither of these situations are particularly interesting, and think that the spell should probably not generate on ghosts.

But both those scenarios are awesome.

In deference to a report, I've removed some posts that were off-topic. If people want to discuss removing ghosts or changing Fulminant Prism, they can start new threads, because this one is about ghosts who cast Fulminant Prism.

e: though I could see extending that discussion to monsters being able to cast Prism in general, because I'm more familiar with it being cast (ineffectually) by Panlords.

I think that if we removed it from generating ghosts it would stop genning on pan lords too (which I think is OK).

Prism seems like a fairly problematic monster spell, as it relies on understanding creature movement. Monsters don't understand player movement at all.
