Concentration rates as one of the best additions to the fifth-edition Dungeons & Dragons rules. In earlier editions, higher-level parties might enter a fight layered with spells like haste, invisibility, fly, blur, protection from energy, and on. Players needed spreadsheets to track their bonuses, while dungeon masters struggled to create any challenge. Concentration simplifies the game by limiting the magical effects in play.
In earlier editions, the same caster behind the buffs could also immobilize foes with Evard’s black tentacles, and then smother them with cloudkill. Now, the need for concentration limits the power of spellcasters, helping to eliminate D&D’s old problem of wizards who surged in power with every level until they overshadowed other classes. (See How fifth edition keeps familiar spells and a Vancian feel without breaking D&D.)
Plus, concentration enriches the game by adding a fresh, tactical element. Combatants can end spell effects by targeting casters and breaking their concentration.
While concentration improved D&D and put wizards in their place, the innovation proved mixed for class archetypes that cross swords and spells.
For exhibit A, see the paladin. In my last game, the party’s smite-happy paladin relished the chance to lock down a monster with compelled duel. This 1st-level spell boosts the paladin’s flavor of champion and protector. But compelled duel requires concentration, so while the paladin trades blows, every hit threatens to end the duel. Paladins want to bear the brunt of attacks, and they lack proficiency with Constitution saves, so their concentration is fragile. Why would a paladin ever cast shield of faith?
Worse, the paladin’s smite spells also require concentration, so even momentary attention to a smite spell ends the compelled duel. With smites serving as a cornerstone of the paladin’s offense, the need for concentration brings some frustration. Spells like magic weapon, heroism, and bless seem perfect for paladins, but all demand concentration.
In the D&D Next playtest, the paladins smite spells skipped the concentration requirement, but spells like banishing smite and blinding smite impose ongoing effects that merit concentration. The designers added concentration to add the tactical element where foes can break concentration to end punishing effects.
The same tension between concentration and a melee archetype hinders warlock hexblades and pact of the blade warlocks who aim to use their pact blade for more than posing. Hexblades gain smite spells that require concentration, yet the class also features spells like hex that demand attention.
Surely rangers suffer the most friction between concentration and the class’s featured abilities. The hunter’s mark spell underpins the ranger’s flavor as someone who targets prey and pursues it to the finish. With a duration marked in hours, hunter’s mark seems meant to last through a ranger’s daily adventures. But the spell requires concentration, so rangers who need another spell lose their mark and what feels like a key feature. Also, rangers who aim to enter melee with say, a sword in each hand, suffer an outsized risk of losing their mark. (This exposes another spot where fifth edition punishes melee archetypes, but I’ve written about that already.)
The D&D design team uses their Unearthed Arcana series to test player reaction to potential game additions. A collection of class feature variants reveals one feature intended to smooth the rough spots from hunter’s mark. Read my annotated description.
1. Instead of changing the base ranger class by adding a new feature missing from the Player’s Handbook, this variant adds an option that replaces a weak class feature. Most players would opt for Favored Foe, but rangers built from the core book keep a unique feature. The D&D design team has chosen not to make changes to the game that supplant anything in the published books. New players should never join a game and then learn that their Player’s Handbook character fails to match the latest rules.
2. The hunter’s mark spell implements a 4th-edition power called Hunter’s Quarry, a non-magical exploit that seemed to behave in some magical ways because the rules said so. Now, the replacement works like magic because it is.
3. First-level rangers can’t normally cast spells, but this feature needs the hunter’s mark spell. This line adds the one spell to a 1st-level ranger’s knowledge.
4. Oddly, the description says “use” rather than “cast”. This shows the designer thinking of this feature as an ability more than a spell. The whole feature description reads like something written by committee, but surely a final version will show more polish.
5. Because hunter’s mark implements a marquee ranger class feature, having to spend a spell slot on it feels like a tax. Here the ability goes tax free.
6. This waives the concentration requirement. Dual-wielding Drizzt admirers everywhere can cheer.
7. Hunter’s mark no longer taxes a ranger’s list of known spells either.
Favored Foe offers a good way eliminate a frustrating edge in the ranger class. I predict we’ll see it in a class options book toward the end of 2020.
