Can You Cast Mind Sliver as a Bonus Action? A Deep Dive into D&D Spellcasting
The short answer is: no, you cannot typically cast Mind Sliver as a bonus action. Mind Sliver, a potent cantrip favored for its psychic damage and debuffing capabilities, has a casting time of 1 action. Only specific spells that explicitly state they can be cast as a bonus action are eligible to be cast in this way. However, as with many things in D&D, there are ways to bend the rules and make the impossible possible, which we will explore.
Understanding Spellcasting Actions
Before diving deeper, let’s recap the basics of spellcasting actions in Dungeons & Dragons 5th Edition (D&D 5e). Each turn in combat allows you one action, one bonus action, movement, and a reaction. Spells fall into different casting time categories:
- Action: Most spells require an action to cast.
- Bonus Action: Some spells, when their description specifies, can be cast as a bonus action.
- Reaction: These spells are cast in response to a specific trigger.
- Longer Casting Times: Spells can also have casting times measured in minutes, hours, or even days.
Why Mind Sliver Isn’t a Bonus Action Spell
Mind Sliver, by default, requires an action to cast. The spell description makes no mention of being cast as a bonus action. To cast it as a bonus action, you need a specific ability or feature that alters the spell’s casting time.
Sorcerer’s Metamagic: Quicken Spell
The most common way to cast Mind Sliver as a bonus action is through the Sorcerer class’s Metamagic feature, specifically the Quicken Spell option.
- Quicken Spell: This metamagic option allows a Sorcerer to spend 2 sorcery points to change a spell’s casting time of 1 action to 1 bonus action.
Therefore, a Sorcerer can use Quicken Spell to cast Mind Sliver as a bonus action, freeing up their action to cast another spell (potentially another cantrip, given the restrictions we’ll discuss below) or take other actions like attacking.
Potential House Rules and DM Discretion
While not RAW (Rules As Written), some DMs may allow custom feats, items, or class features that could potentially grant the ability to cast Mind Sliver as a bonus action. This is entirely at the DM’s discretion and would need to be clearly defined.
Spellcasting Restrictions: The Bonus Action Spell Rule
It’s crucial to remember the following rule when casting spells, especially when involving bonus actions:
“A spell cast with a bonus action is especially swift. You must use a bonus action on your turn to cast the spell, provided that you haven’t already taken a bonus action this turn. You can’t cast another spell during the same turn, except for a cantrip with a casting time of 1 action.”
This means that if you cast Mind Sliver as a bonus action (using Quicken Spell, for example), the only other spell you can cast on that same turn must be a cantrip with a casting time of 1 action. You couldn’t cast a leveled spell as your action.
Synergy with Mind Sliver
The primary reason players want to cast Mind Sliver as a bonus action is to pair it with another impactful spell on the same turn. The cantrip’s debuff (-1d4 to the next saving throw) is designed to set up another spell that relies on a saving throw.
Example:
- Bonus Action: Sorcerer uses Quicken Spell to cast Mind Sliver.
- Action: Sorcerer casts Hold Person (a spell that requires a Wisdom saving throw) at the same target, hoping that the -1d4 penalty will increase the chances of the target failing their save.
Why Mind Sliver Is Still Powerful, Even Without a Bonus Action
Even without the ability to cast it as a bonus action, Mind Sliver remains a strong choice for many spellcasters due to:
- Psychic Damage: Relatively few creatures are resistant or immune to psychic damage, making it a reliable damage type.
- Saving Throw Debuff: The -1d4 penalty to the target’s next saving throw is valuable, even if you can’t immediately capitalize on it on the same turn. It can still help allies land their spells.
- Cantrip Versatility: As a cantrip, it can be cast an unlimited number of times without expending spell slots.

Frequently Asked Questions (FAQs)
1. What are some other ways to get bonus actions in combat?
Beyond Sorcerer’s Quicken Spell, many classes have features that grant bonus actions. Rogues have Cunning Action, Monks have various ki-powered abilities, and some spells (like Healing Word) can be cast as bonus actions.
2. Can a Bard cast Mind Sliver as a bonus action?
No, not inherently. A Bard doesn’t have a feature like Quicken Spell. They could potentially acquire it by multiclassing into Sorcerer or through a feat like Metamagic Adept (from Tasha’s Cauldron of Everything).
3. Does the -1d4 from Mind Sliver stack with other debuffs like Bane?
Yes, debuffs generally stack unless they are the exact same effect from the same source. Mind Sliver‘s -1d4 will stack with the -1d4 from Bane, resulting in a -2d4 penalty.
4. Can you counterspell Mind Sliver?
Yes, you can counterspell Mind Sliver. It’s a spell, and therefore a valid target for Counterspell.
5. What happens if a creature succeeds on the saving throw against Mind Sliver?
If the target succeeds on the Intelligence saving throw against Mind Sliver, they take no damage and do not suffer the -1d4 penalty to their next saving throw.
6. Is Mind Sliver a good spell choice for all spellcasters?
It depends on the spellcaster’s build and playstyle. It is a good choice if your character benefits from using Psychic damage. Otherwise, other cantrips may be more beneficial.
7. What classes can learn Mind Sliver?
Sorcerers, Wizards, and Warlocks can learn Mind Sliver.
8. Does Mind Sliver get stronger at higher levels?
The damage die of Mind Sliver increases at higher levels, similar to other damage cantrips:
- 5th Level: 2d6 psychic damage
- 11th Level: 3d6 psychic damage
- 17th Level: 4d6 psychic damage
The -1d4 penalty remains the same.
9. Can you Twin Spell Mind Sliver?
No. Twinned Spell works on spells that can target one creature at level 1. Mind Sliver can target only one creature at all levels.
10. If I cast Mind Sliver as a bonus action, can I still cast a leveled spell with my action next turn?
Yes. The restriction on casting a leveled spell only applies on the same turn you cast a spell as a bonus action. On subsequent turns, you are free to cast leveled spells as normal.
11. What are some good spells to pair with Mind Sliver’s debuff?
Any spell that requires a saving throw benefits from the -1d4 penalty. Hold Person, Banishment, Hypnotic Pattern, and other control spells are excellent choices. Spells that deal high damage on a failed save, like Fireball or Lightning Bolt, can also be good options.
12. Can I use a reaction to cast a spell on the same turn I cast Mind Sliver as a bonus action?
Yes, reaction spells are separate from the bonus action spell rule. You can cast a reaction spell on the same turn as a bonus action spell (and a cantrip with a casting time of 1 action).
13. Can I use Action Surge to cast Mind Sliver twice in one turn?
Yes, a Fighter with the Action Surge feature could cast Mind Sliver twice in one turn, assuming they haven’t already used a bonus action spell.
14. How does Mind Sliver interact with disadvantage on saving throws?
The -1d4 penalty from Mind Sliver is applied after disadvantage is rolled. The target rolls two d20s, takes the lower result, and then subtracts 1d4 (assuming they failed the initial save against Mind Sliver, of course).
15. Are there any magic items that let me cast Mind Sliver as a bonus action?
There are no official magic items that grant this specific ability. However, a DM could create a custom magic item with this property. Always check with your DM regarding homebrew items.
