Freedom of Movement

So one thing I thought about recently was Freedom of Movement. Of the the big benefits of Freedom of Movement is that you are essentially immune to grappling. This is incredibly important because grappling, especially at higher levels, can basically be an insta-kill. People may complain about 'save or die' effects, but grappling is much worse because in many grappling checks you essentially can't win. For example, compare a Remorhaz against a 7th half-orc barbarian. The barbarian has a 22 strength using gauntlets of ogre strength. He can rage to bring his strength to 26. This gives him a total grapple of 15. The Remorhazes grapple is 23 which gives it an 8 point advantage. This gives the barbarian a19.5% chance of not getting grappled and then not getting swallowed. His companion, the halfling thief, who moves to flank has a 14 strength and a total grapply bonus of +3. He can not win. If bitten by the Remorhaz he will be automatically grappled and next round he will be swallowed and will take 8d6 per round. The examples get even more extreme as you go up levels. Big grappling creatures like dragons, purple worms, and remorhazes can grab a character extremely easily and characters have no hope of beating their grapple rolls. They can then do something horrible like fly high up in the air, dive into lava, or simply swallow the player with almost no chance of the player escaping.

So the best defense against this is the spell Freedom of Movement. It becomes available at 7th level. Rings of Free of Movement also become available at 7th level. These make you completely immune to grappling creatures. The spell lasts 10 minutes per level so it can take you through multiple encounters, but casting the spell on your entire party can drain the resources of even a high level caster so the ring is also key. This spell is one of those massive game-changers. If you have it you can survive and if not you are screwed.

What might be nice is spells and powers in the middle. For example how about a 3rd level, hour/level spell that gives you +6 grapple per size category the grapple has on you.
