You blast the mind of a creature that you can see within range, attempting to shatter its intellect and personality. The target takes 4d6 psychic damage and must make an Intelligence saving throw.
On a failed save, the creature's Intelligence and Charisma scores become 1. The creature can't cast spells, activate magic items, understand language, or communicate in any intelligible way. The creature can, however, identify its friends, follow them, and even protect them.
At the end of every 30 days, the creature can repeat its saving throw against this spell. If it succeeds on its saving throw, the spell ends.
The spell can also be ended by greater restoration, heal, or wish.
* - (a handful of clay, crystal, glass, or mineral spheres)
Since no one has responded, the additional portion of spell are separate from the ability scores, so while a Headband of Intellect would set your int to 19, effectively the rest of your brain is still so scrambled you can't do anything else that's described.
Silky question. If I cast this on, say, a mimic and knock it's int down to 1, could I then cast awaken on said mimic? Once it's int is up to 10, it could maybe beat the spell dc and get it's charisma back. Basically, I want my bard to become like venom and I think a mimic gets me pretty close.
People generally seem to agree that feeblemind + awaken would work, but awaken can only target beasts or plants, and a mimic is a monstrosity. It's specifically mentioned that some mimics can evolve greater cunning, though.
This spell became even more abusable when they added Raulothim’s Psychic Lance
Now after using Feeblemind to drop the target’s Intelligence to 1, you can pummel them with Psychic Lances every turn to always incapacitate them if your spell save DC is 16+.
Granted, they need to be vulnerable to Incapacitation, and not have proficiency on INT saves, but even the Aspect of Tiamat and the Chromatic Greatwyrms are vulnerable to this. (The Aspect of Bahamut is not as susceptible to this because of his INT save Proficiency)
There’s a function for temporary stats iirc
And 14nth level monks!
The problem is that both Tiamat and Bahamut has legendary resistances, and you only have 2 8th level spell slots even at level 20 for wizard, or you could cast this spell to burn their legendary resistances
Why isn't this a sorcerer spell? It would have been PERFECT for aberrant mind. Breaking your foes mind with alien thoughts is so fitting.
I had this cast on me the other night at the end of the campaign when 2 PCs betrayed me and the rest of the party. A homebrew rule allowed the warlock to change my save from wisdom to dex. My wisdom would have been +14 while my dex was +2. Needless to say I failed the save and was defencless as they murdered me.
unless you use something to remove its effects
Stupid question, can the creature effected by this spell attack? It says it still can recognize and defend its friends, but can it attack by itself?
This happened in my campaign not too long ago - I cast Feeblemind on the fighter, who failed the save. I ruled he could attack creatures who attacked him.
Could they even attune to a headband of intellect since they can't activate magic items?
By the time the party is encountering enemies that are using this, the healer should either already have access to or be very close to obtaining Greater Restoration.
Rules as written, dispel magic does end the effect. Rules as intended, it does not end the effect. Dispel magic does not say that it only works on non-instantaneous spells, that's something that Crawford has said after the fact. Dispel magic just says that "any spell on the target ends" and that lines up with feeblemind saying that you have to save every 30 days to "end" the spell, or cast greater res, heal, or wish to "end" the spell. As written, this is an effect that does not end until something ends it, and dispel magic says that it can end the spell. Crawford's ruling is also not gospel.
This is the "Screw you, you don't get to do anything" spell.
DMs have fun giving something like your Lich this.
For why it doesn't work with dispel magic, I believe it's because it intentionally is about breaking the mind and essentially just giving a disability to someone instead of putting a spell on them. So while the source of the effects is magical, the effects themselves are based on physical injury not magic.
Perfect setup spell for a magic jar host body
...so the damage can't be blocked, the saving throw is for the next effect after the damage has already been taken
But what if the healer is the one on the receiving end of this spell? They aren't able to cast magic while feebleminded, so it wouldn't be possible to restore their own mind
