My point, Mike, was that a pin effect doesn't belong in the Summoned Force effect group. It belongs in the binding effect group. Having a spell that changes effect group based on how you cast it seems needlessly complicated, although I suppose there is what one might consider precedent. Still, I'm not personally sold on idea as a whole. I think the concept is interesting, but I feel the implementations suggested here are needlessly complicated and divergent from the current rules system.
I do agree that Celestial is somewhat shafted in that most of the best status effects are Earth only; all the Curses and all the Necro ones. Since status effects are often more useful than straight damage, it does seem somewhat unfair that the theoretical offensively minded school possesses far fewer of them. I'm pitching the idea of an Eldritch Force spell that limits the target to walking speed to my chapter owner. I feel it should be called Hobble, as in "With Eldritch Force I build a Hobble!", but apparently that could be conflated with Hobling. Personally, I find that hilarious, but you can't win 'em all.
Another idea that literally just popped into my head is introducing some very limited Illusion spells. Well, I've wanted to do it before, but I think I've thought of a few that could be made to work.
Phantom Image - This would essentially be a Magic Armor and a Spell Shield in one spell. However, it would take up the slot of both the Spell Shield and Magic Armor. I feel it should be placed at 3rd level, since it would be a Spell Shield that could get lost to a "2 Normal". However, it would pave the way for:
Illusion Image - This would be a Phantom Image with three charges. It would have to be 8th level at least, and putting it at 9th would conflict with the almighty Prison. Again, the balance is that it's even more of a gamble than Spell Shield. Yes, it could block three Deaths in a row, which is incredibly powerful; it could also absorb three simple weapon blows and be gone. Since you would have to announce "Illusion Image" when hit, anyone paying attention can respond accordingly.
Calming Vision - This is where the status effects come in. Calming Vision would be 4th level. Anyone hit with Calming Vision would stand still or sit down, entranced by the peaceful images in front of them that only they can see. However, any harmful effect would stir them from their reverie and restore them to normal. Any weapon blow and the target wakes up, immediately able to respond. This means that they could use any smart defense in response, like Parry or Resist Poison.
Enthralling Vision - Works like Calming Vision, except the target cannot respond at first when struck. This would have to be 8th level, since it is as debilitating as a Paralysis.
The Visions would not work on mindless or spiritless creatures.
