Optimising For Concentration In D&D 2024

Maintaining concentration can be tricky, but you can improve the odds with a few tricks.

Many spells in D&D 5e require extra effort to maintain. This is represented by the concentration mechanic. It prevents spellcasters (normally) from maintaining multiple, powerful, ongoing spells while giving enemies the opportunity to end these spells early.

This means that increasing the odds of maintaining your concentration is really important. If you lose it, then you’ve wasted a potentially important spell slot and ongoing effects you were relying on might end. It also means you want to have a spread of concentration and non-concentration spells in your spell list.

In this article, I’ll take you through how concentration works, how you can optimise for it and how to tackle enemies using concentration spells.

How does concentration work?

Many spells require concentration to maintain. If concentration ends, then the spell ends. There are a few things that can end your concentration on a spell:

Spell duration ends: If the spell has been maintained for the duration, it will end.
Caster chooses to end concentration: A caster can simply choose not to maintain concentration on a spell. No action is required for this.
Initiate concentration on another spell or effect: If you start casting another concentration spell or another effect that needs concentration, then concentration on the initial spell or effect ends.
Taking damage: If you take damage while concentrating, you must take a constitution saving throw to maintain concentration. the DC is either 10 or half the damage taken rounding down and no higher than 30.
Incapacitated or dead: If you gain the incapacitated condition or die, you can no longer maintain concentration. Being knocked to 0HP will gain you the incapacitated condition. Other conditions also cause incapacitated including; paralyzed, petrified, stunned and unconscious.

How to better maintain concentration

When it comes to maintaining concentration, your biggest threat will come from taking damage. You can do some thing to reduce the damage you take including:

Avoid attacks: You probably can’t stop yourself being the target of all attacks, especially since blasting nasty concentration spell effects might make you the target of more attacks. You can try and stay away from danger though. Flight, hiding, invisibility or just attacking at range can help here. You can also use natural obstacles like buildings and walls to get out of line of sight or at least provide cover to improve your AC.
Improve your AC: On that note, one of the most robust ways to avoid damage is to have a high AC. If you’re harder to hit, you’ll need to take concentration saving throws less. Armor (or the mage armor spell), shields, increased dexterity, AC increasing spells (like shield or shield of faith), cover, species traits like from a warforged or even class and subclass features like a draconic sorcerer’s unarmored defense can all help to increase your AC.
Improved saving throws: This will not only help you avoid damage (as many spells and effects can cause damage on a failed saving throw or at least more damage) but can also help you avoid nasty conditions that might cause you tone incapacitated. Some species get improved saving throws like the Gnome does from magic, classes also get proficiency in certain savings throws and the resilient feat will let you grab proficiency in another ability score to improve that saving throw.
Improved concentration saving throws: You can also improve your concentration saving throws directly but more on that in the next section.

How can you improve concentration saving throws?

Concentration saving throws rely on constitution. Anything that helps your constitution, will also help your concentration, but there are a few extra things you can do specifically to optimise for concentration saving throws:

Increase constitution score: The easiest way to do this is to increase your constitution ability score. Every class benefits from more resilience so this is always a good ability score to invest in, but spellcasters have an extra reason to do so. You will have to balance this with your prowess in other areas though.
Constitution proficiency from your class: Some classes naturally gain proficiency in constitution saving throws, these include; sorcerers, artificers, fighters and barbarians. I wouldn’t really recommend taking levels in barbarian for a spellcaster, but a fighter could work (or you could just be an eldritch knight).
Constitution proficiency through the resilient feat: If your class doesn’t give you constitution proficiency, then you can grab it through the resilient feat.
War caster feat: War caster will grant advantage on concentration saving throws.
Take the eldritch mind eldritch invocation: Warlocks can take eldritch mind from level 1 to gain advantage on concentration saving throws.
A paladin’s aura of protection: Standing within 10ft of a level 6+ paladin will grant a boost to your savings throws (including concentration) equal to their charisma modifier.
Get bardic inspiration from a bard: Bards can give you a one off boost to a saving throw each time they grant you bardic inspiration.
Artificers can replicate a mind sharpener: This will let you succeed a failed concentration saving throw up to 4 times per day if you use your reaction.
Moon druids and improved circle forms: From level 6, moon druids can add their wisdom modifier to their constitution saving throws.
Altered d20 tests: Some features and feats will let you change, reroll or gain advantage on your d20 test. This includes things like the lucky feat, the diviner’s portent dice and the Halfling’s luck trait.

Spell lists and concentration

The first time I played a spellcaster, I looked for all the best spells possible for that caster (a sorcerer) and added them to my spell list. The problem I had is that many of the most potent effects are those that require concentration. It meant that once I started concentrating on a spell, I had little else I could do except cast cantrips and maybe magic missile.

In reality, you want a balance of effects that gives you plenty of options on your spell list. This means some concentration spells, but it also means ensuring you have spells you can cast without using concentration. Make sure your spell list isn’t overwhelmed with concentration spells.

Dealing with enemies using concentration spells

Sometimes, you may face an enemy spellcaster that casts concentration spells. Some of these can be very problematic for the party like banishment or eyebite. Ending that concentration spell can be key to surviving an encounter.

Attacking the spellcaster with plenty of attacks (especially high damage attacks) can help end their concentration. This might mean focusing fire on them. You could also cause them to have the incapacitated condition.

On top of this, you can cause effects on them that make them more likely to fail a saving throw. This could be a spell like bane, synaptic static or mind sliver. It could also be something like a diviner’s portent feature or the lucky feat. Dispel magic could also be used to end a concentration spell. There’s also the mage slayer feat which will give disadvantage to your target on concentration saving throws.

You could also try to prevent them casting these spells altogether by using a spell like silence or counterspell.
