Probably the best solution is to get rid of immunities entirely. Then there's no problem.

Actually, resistances (especially multiple) have the same problem. A glowing ball doesn't do much more than tickle you, as soon as you have double fire resistance or better. And that's very easy to get, there are multiple guaranteed artifacts with resistances.

Maybe ancient wyrms should stop casting glowing balls entirely. They can hit you in melee for hundreds of damage, casting a very weak spell instead is a waste of turns.

Only if all monsters in the game that have an immunity are also deprived of it.

I disagree with this for precisely the reasons JS has stated - these spells have the capability to be dangerous even if you're immune (I should know, I've died!)

Yes, with the new freezing blood corruption. That is even more possible.

I'm not sure if you're being ironic. But if you aren't, come on, immunity is a distinctive feature of the game with lots of strategies revolving around it. You can't just go and remove it. You'd be removing a lot of interesting decisions and strategies for the game.

Make certain immunities rarer, OK, but remove immunities altogether, hell no!

Voted no, because in some situations monsters casting Frost Bolt is actually what you want.

I'm assuming you mean that in a negative way.

If so, yes. You want the monster to cast the spell at the player character a few times, maybe slowing the player character down considerately, then realize that the player character is most likely immune and nice and slow and come in for the kill. Which will happen automatically of course when this suggestion is implemented.

Well, no - c.f. red piranha lake, eliminating creatures behind you [think shadow wyrms; giant slugs & cats]. There are actually some very neat tactical uses of breath attacks esp. when you're immune/heavily resistant.

This RFE is about ice bolt though, which a monster does not cast either through another monster or past the PC.

This suggestion will make the piranha lake more difficult to freeze over with an Ogre Magus, yes. I was misunderstanding what paivi was referring to. Which was in a positive way.

Don't shadow wyrms breathe ice [as opposed to casting ice], often eliminating the shadows they've surrounded you with? I'm not certain I really understand this RFE if it's only casting ice - that seems like an oddly restricted interpretation of changing attacks in response to what the PC is immune to.

Oh, that was to keep item destruction as a good reason for the breathers to continue using their attacks.

I don't recall Shadow Wyrms breathing ice.

Stingray, both positively and negatively, I guess, although I wasn't really thinking about the monster's point of view. For the player, it's a viable way of building bridges over normal rivers too, especially if you can swim. (And why would you want to build a bridge if you can swim? Well if you have no waterproof blankets...)

I feel that this suggestion would add very little to the game while taking away some fun tactical aspects that reward creativity.

Well, just remember that Ogre Magi are pretty stupid. So they will cast the spell pretty much, before they realize it is better to bash this one.
