A Title Much Cooler Than Anything on the Old Site
There are a lot of threads about the Wall of Force ("WoF") spell and how DMs can avoid having it break their games. But I'm looking for feedback on my intended use by a monster and my understanding (or lack of understanding) of the RAW for this spell.
In an upcoming game, the party will need to infiltrate a mind-flayer colony, where they will encounter an elder brain (EB).
I'm interpreting the EB's glass-like protective layer (described under Elder Brain Resting Pool in Volo's Guide to Monsters [VGM] page 78) to be a WoF cast as a lair action (VGM 173).
An EB can keep recasting the WoF every turn if it needs to. If it loses concentration, it just has to recast it on initiative count 20 the next round.
So how can the party harm the EB? Here is how I interpret the RAW for WoF. I'm interested in whether you think I'm interpreting them correctly. Yes, yes, DMs can interpret and implement rules however they want, etc. But my players are tactical and we enjoy a bit of rules lawyering. Hand waving things like this isn't very satisfactory. Ultimately, I'm the judge but I want it based on a reasonable interpretation of RAW.
So, with that said, I don't have any issue interpreting the first paragraph of the description of the WoF spell. It is the second paragraph that I want to make sure I'm getting right:
My anticipated rulings:
Reading other threads that complain about players having this spell makes me think I'm missing something. But I see a number of ways to deal with WoF. Here I'm not worried about players breaking the game with it, but that it doesn't make the encounter impossible...to more I reread and think about the WoF spell, the more I think it is not the impossible-to-overcome broken spell so many make it out to be.
Let me know if I'm way off base or missing some nuances.

So, with that said, I don't have any issue interpreting the first paragraph of the description of the WoF spell. It is the second paragraph that I want to make sure I'm getting right:
Nothing can physically pass through the wall. It is immune to all damage and can't be dispelled by dispel magic. A disintegrate spell destroys the wall instantly, however. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall.
My anticipated rulings:
- While the WoF covers it, the Elder Brain is immune from any weapon attacks. Nothing can slash, pierce, bludgeon, etc. through the WoF to damage the EB.
- There is, however, nothing in the description that indicates that the wall is immovable. In other threads I've read, everyone assumes it is. Why? Where is that stated? Nothing can pass through it. Nothing can damage it. If you have a WoF sphere surrounding you, why can't a giant kick it (and you in it) like a ball? If a dome, why can't it be lifted? Force is "pure magical energy focused into a damaging form." (PHB 196). WoF force is not a damaging form, but pure magical energy focused into a form. Otiluke's Resilient Sphere is a "sphere of shimmering force" that can be pushed, rolled, picked up, and moved by other creatures.
- Since a Wall of Force should be movable, with a big enough hit, you may cause the EB to smash against the side, basically causing an Elder Brain concussion. A smart EB will have the inside of a WoF sphere filled with brine, which will mitigate that, but it should be one non-magical way to cause some damage. I'm thinking that if a player rolls a crit, they jar the EB within its WoF enclosure so hard that it take half the normal damage of what the hit would cause if it was made directly to the brain.
- "Nothing physical can pass through the wall" includes energy and magical forces (where "force", "energy" or "light" are used in the description text. So most attack spells will not penetrate, but something like Vicious Mockery would cause damage through a WoF. This also ties in with the EB's protective layer as described in VGM which states that psychic attacks can pass through. Other spells I would think could be used to harm or control creatures behind/enclosed in a WoF include: Weird, Banishment, Tasha's Hideous Laughter, Slow, Sleep, Power Word Kill, Phantasmal Killer, Phantasmal Force, Otto's Irresistible Dance, Modify Memory, etc.
Many of these are illusions, and psychic in nature, which integrates well with EB lore in VGM. But I think it also gives options to those who think WoF breaks the game. If you have a Mystic or an Illusionist, they can still mess you up while you're cocooned in your WoF. - It goes both ways. Nothing physical can pass through. Any attacks or spells that cannot enter from the outside, also can't come from the inside and go out.
- Concentration. WoF is a concentration spell. Those who claim it is game breaking don't seem to show much creativity in the myriad of ways concentration can be broken. Besides taking damage or casting another concentration spell, you could create distracting illusions, cause confusion and chaos on the battlefield, "push their button" causing them to lose their temper and concentration. EB are so full of themselves that they may lash out if mocked and belittled, given a high enough skill check.
