List of bugged spells

This list aims to catalogue spells which does not function as would be expected based on its tooltip, or that has other problems - or missing information - in its description, function, or location. This list is unlikely to be comprehensive as it is likely there are many issues with items of which we are unaware.

As this list deals with problems that have a high likelihood of being changed in patches and hotfixes, it is likely that entries will be incorrect following an update.

All entries are currently correct as of Hotfix 29.

Spells

Name	Bugs
Blade Barrier	Spell save DC for this spell is not functioning properly. The initial spell save DC for damage caused by casting and entering the wall is fixed at 15, the DC for starting a turn inside the wall is fixed at 3, and the DC for starting a turn near the wall is fixed at 10.
Blink	Despite purposely ignoring the functor which breaks Concentration, a StatusGroup error still breaks Concentration when vanishing.
Brace (Melee)	When used with Savage Attacker, it will roll each dice 3 times and use the highest result. The tooltip is showing 4 rolls but it appears to be a bug as of patch 6. When used with Savage Attacker and Great Weapon Fighting, it will do a first roll and reroll if it's a 1 or 2, and then roll 2 more times and use the highest result. The tooltip is showing 4 to 6 rolls but it appears to be a bug as of patch 6.
Bulwark Rebuke	This ability incorrectly calculates half damage on a saving throw as 1d4Force instead of (2d4)/2Force.
Concussive Smash (Spiritual Weapon)	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Counterspell	Arcane Ward will only ever be fed 3 charges, regardless of spell Level used, due to how an additional hidden Counterspell is cast based on success/failure
Cutting Words	Cutting Words may target friendly characters whose failed rolls prompted the effect, as opposed to the enemy character who rolled a save
Dawnburst Strike	The description in-game notes an incorrect DC 13  Constitution saving throw save. It requires a Weapon Action save with a +2 DC bonus. Despite the in-game description stating only enemies in the light must save against becoming blinded, the blindness affects all creatures in the area, even allies.
Death Burst (Mud)	The tooltip states that this action deals 4d6Bludgeoning damage, but it actually deals 4d6Force.
Defensive Duellist	Unlike similar reactions (Shield Master: Block), the icon for Defensive Duellist in the reactions tab does not "gray out" when the reaction is unavailable due to an incompatible equipped weapon.
Deflect Missiles	This feature seems to behave weirdly with certain weapons, possibly due to bugs. Deflect Missiles does not trigger at all against attacks from Giantbreaker. Against dual wielding Hand Crossbows, the first attack will always hit; the second attack can be reduced by Deflect Missiles, but Deflect Missiles (Return) never triggers.
Detect Thoughts	Despite the tooltip saying this spell uses either Intelligence or Wisdom, only the creature’s Intelligence is used, even if its Wisdom is higher. This is likely an oversight.
Diving Strike	If this attack misses and  Reckless Attack is triggered in response, the attack roll will not actually get rerolled, so it will always still miss. However, if Reckless Attack is already active, the attack roll will be made with Advantage as expected.
Find Familiar	There are many bugs associated with familiars, with many of them not getting proper bonuses to attacks or damage based on their attributes, and some of them not requiring attack rolls for their basic attacks at all. [Needs Verification]
Fist of Four Thunders	This spell is missing the trigger for  Martial Arts: Bonus Unarmed Strike, and will not grant its effect.
Fly (Illithid Power)	While it is supposed to replace the Jump action's keybinding, this interaction is unreliable and seems to be bugged. It will often initially work, but then be reset to Jump when e.g. loading a saved game.
Grasping Vine	When upcast, this spell requires an Action instead of a Bonus action. This is likely a bug.
Greataxe Slash	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Greatsword Slash	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Halberd Slash	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Heart of the Storm: Lightning	Despite its tooltip stating otherwise, Heart of the Storm activates on cantrips.
Heart of the Storm: Thunder	Despite its tooltip stating otherwise, Heart of the Storm activates on cantrips.
Hellflame Cleave	Despite the tooltip saying that Hellfire ignores resistances and immunities, it does not.
Heroes' Feast	This spell sometimes doesn't make Wisdom Saving throws with Advantage. [Needs Verification] It seems to be related to Potion of Angelic Slumber or Orin.
Immolating Gaze	The additional damage against  Burning creatures is currently bugged; it only applies to creatures that succeed the saving throw. On a failure the damage is still 2d8.
Invoke Duplicity	The illusion is destroyed when it is targeted by any effect, even if it is the target of a friendly  Mass Healing Word.
Lacerate (Spiritual Weapon)	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Magic Awareness	This effect incorrectly provides a 1d4 bonus to Saving Throws instead of adding a character's Proficiency Bonus.
Maul Blow	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Multiattack (Malus Thorm)	Despite what his  Multiattack: Wounded passive implies, Malus Thorm can use this attack at any time, provided he is not wielding one of his surgical tools granted by  Request Surgical Instrument.[Needs Verification]
Ochre Sputum (grease)	The in-game description mentions it creates an  Acid surface when instead it creates a  Grease surface.
Phalar Aluve: Shriek	Despite its description, Shriek affects all saving throws and attack rolls made by the affected target.
Phalar Aluve: Sing	The in-game tooltip specifies that the bonus to saving throws applies to Charisma, Wisdom, or Intelligence ones. This is not true. The bonus applies to all saving throws, including death saving throws.
Piercing Strike (Spiritual Weapon)	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Produce Flame	The damage on the tooltip for Produce Flame is not marked correctly for the increases at level 5 and 10. The tooltip for the throwing action,  Produce Flame: Hurl, is marked correctly, and the damage scales correctly. The version of this Cantrip granted by the Asmodeus Tiefling subrace uses the character's Wisdom modifier to hurl the flame, rather than Charisma as stated in the  Produce Flame: Hurl tooltip.
Produce Flame: Hurl	The version of this Cantrip granted by the Asmodeus Tiefling subrace, uses the character's Wisdom modifier to hurl the flame, rather than Charisma. See: Tiefling - Bugs. On Clerics the damage on the tooltip for Produce Flame is not marked correctly for the increases at level 5 and 10. The tooltip for the throwing action,  Produce Flame: Hurl, is marked correctly, and the damage scales correctly. It has the same chance to hit as  Guiding Bolt.
Prowl	The bonus damage from Prowl only works at druid levels 6 or 7. See the Bugs section of  Prowling for details. At druid levels 6 or 7, you will continue to concentrate on Prowl even after the invisibility ends. This will prevent you from recasting Prowl and the tooltip will say "Must take a Short Rest". However, you can manually end your concentration which will allow you to freely use Prowl again. This does not apply to druid levels 8 and above for the same reason that the bonus damage is broken.
Shield (spell)	Due to a scripting error, this spell does not grant charges of  Arcane Ward.
Shield Blow	The description of this ability states it requires a Dexterity saving throw. This is incorrect, as it requires a Strength saving throw.
Shield Master: Block	This passive currently provides no effect on a failed save.
Song of Rest	An exploitable bug presently exists wherein this ability incorrectly recharges whenever the party fast travels to a different region (ie the dialog box for confirming travel to a different region appears), allowing unlimited short rests. Most recent test Patch 6, Hotfix 25.
Spear Thrust	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Storm's Fury	Even though the passive feature states it deals Lightning, the reaction deals strictly Thunder damage only.
Synaptic Consumption	It is dangerous for a creature to fail a save against this ability: if failing the first saving throw against this and starting with an ability score of 11 or below, the affected entity is inflicted with  Atrophy at the start of its turn and dies instantly, without another saving throw. This happens whenever any remaining ability score is the same as or lower than the penalty that would be applied at the start of its turn. Consider the following two examples: Example one: during combat, a full-illithid creature uses this ability on an entity whose lowest ability score is 13. A save is rolled immediately and, if failed, the target's abilities are reduced by 5, where the lowest is reduced to 8 (13-5). At the start of the afflicted creature's turn (in the same round) another save is rolled: if failed, that ability is reduced to a 7 (13-6). At the start of the entity's next turn, no save is rolled because, at the start of its turn, its lowest ability score (now a 7) is the same as the penalty that would be applied (-7); it dies instantly from  Atrophy. Example two: during combat, a full-illithid creature uses this ability on an entity whose lowest ability score is 11. A save is rolled immediately and, if failed, the target's abilities are reduced by 5, where the lowest is reduced to 6 (11-5). At the start of the entity's turn (in the same round), no save is rolled because, at the start of its turn, its lowest ability score (now a 6) is the same as the penalty that would be applied (-6); it dies instantly from  Atrophy.
Tides of Chaos	Tides of Chaos as a passive toggle is currently (as of v4.1.1.6072089) bugged and does nothing; it is only usable as a reaction.[Needs Verification]
Trident Thrust	The in-game tooltip is incorrect - all the damage dealt is Force damage.
Trip Attack (Ranged)	Despite the tooltip stating it lasts for one turn, Prone afflicted by this attack will last until the target's Long Rest (or until helped).
Vow of Enmity	As of Patch 7, a Paladin can cast Vow of Enmity on themselves to gain Advantage on Attack Rolls against all targets for 10 turns.
Wall of Fire	The saving throw for ending turn inside the wall is not shown in the combat log. Spell save DC for the damage when exiting the wall is fixed at 10.
Wall of Thorns	The in-game tooltip says the duration is 1 turn, but this is incorrect. The duration may be until Long Rest. Spell save DC for Wall of Thorns is currently fixed at 3, and Entangling vines is at 12. (checked in Hotfix #29)
