Rogue 101: Assassin

Tags Class Guides Class 101 Rogue 101

Class is back in session. This week, walk with silent footfalls and carry only weapons small enough to conceal until they appear mysteriously between our enemies’ ribs. Few mortal beings can deal as much damage in a single turn as a rogue who practices the art of assassination—but the act of killing with a single blow requires special preparation, and a DM who weaves scenarios where you can attack from surprise.

We’ve completed our first full rotation of the twelve classes, and exhausted all the content that the Basic Rules have to offer—as far as classes go, that is. This next wave of the Class 101 series will appraise every subclass within the Player’s Handbook and break down each subclass’s strengths, weaknesses, thematic elements, and everything else a player would want to know before playing that subclass. Because of this, you will need to own the Player’s Handbook (or purchase the subclass a la carte on the Marketplace) in order to make full use of this series.

Check out the other guides in the Class 101 series, like the broad overview of the rogue class in Rogue 101: A Beginner’s Guide to Stealth and Subterfuge, and Rogue 101: Thief. If you’re interested in playing other classes, check out the entire Class 101 series.

Story of the Assassin

An assassin waited upon a rooftop in a small farming village. She perched behind a chimney, staring at the windows of a small country inn. A harvest moon hung overhead, and the only sound in the air was that of a rusty vane creaking in the wind. After months of searching, weeks of disguises, and countless insufferable hours of favors and honeyed words, she had found him. Her eyes narrowed, and she peered into his window. The yellow glow of his room’s lamp filtered through his curtained window onto the snow. He’s not above the ground floor, she thought. Arrogant bastard.

Then the lamplight flickered out. The assassin smiled. She leapt from rooftop to rooftop, until she reached the inn her target was hiding in. She clambered quietly down the gutterpipe and set one foot deftly on his windowsill. No trace would be left in the snow beneath his room. Not a trace of her murder would be found—save the ultimate proof.

She opened the window. The room was silent. Less than a minute later, she left, and was never seen in that village again. The next day, the target never left his room. He had told the innkeeper that he was to remain undisturbed when he bought the room, and so no maid came to bother him. It wasn’t until the stench came wafting out a week later that someone dared enter. And by that time, the assassin was over a hundred miles away, never to be found.

Assassin Features

Rogues trained in the art of assassination are renowned for the ability to deal massive damage to unsuspecting foes—but that’s not the only trick they have up their sleeves. The rogue gains access to four subclass features, but many of them skew late. Though you gain access to the first at 3rd, you must wait until 9th for your next, with your final two features eventually coming at 13th and 17th level. You can read all of the Assassin features in the Player’s Handbook. In summary, your subclass features allow you to:

  • Deliver lethal blows to unsuspecting enemies.
  • Create a false identity to help you infiltrate your target’s defenses.
  • Study another person’s behavior to mimic their mannerisms.
  • Deliver even more deadly strikes to unsuspecting enemies.

 

Benefits of the Assassin Archetype

In terms of combat abilities, the assassin is an incredibly straightforward archetype: attack your enemies before they have the chance to attack you—especially if they don’t even know you’re there. Your best turn in combat will invariably be the first turn. After that, you act more or less exactly like any other rogue, unless there are other foes that you can try to surprise and assassinate before they’re aware that a fight’s broken out.

The Assassinate feature, which you gain at 3rd level, seems remarkably powerful on the surface. While it is legitimately powerful, it does have some confusing wording that can lead you to believe it’s more vicious than it actually is. This relates to its “automatic critical hit” effect, which doubles all dice in your attack—including Sneak Attack dice. An attack is only an automatic critical if the creature you’re attacking is surprised. This means that the creature CAN’T be aware of your presence, or that a fight is happening at all. Surprise only happens at the start of a combat encounter, and only when someone in combat is totally unaware of any of their attackers.

Beyond your combat abilities, the assassin gets a suite of social abilities that can give you total mastery in the art of disguise and deception. Your Infiltration Expertise and Imposter traits are both broad in scope, allowing you to fabricate false identities and even assume the identity of someone else. Beyond simply assuming someone’s appearance, like what a changeling might do, these traits allow you to believably mimic this person’s mannerisms and even their handwriting, allowing you to forge documents. These traits are incredibly powerful in an intrigue-focused campaign where words and letters are just as powerful as swords and spells.

Drawbacks of the Assassin Archetype

The Assassin archetype’s greatest noncombat strength is, ironically, also its greatest weakness. The Infiltration Expertise and Imposter class features are potent in the right circumstances, but have precious little use outside of that particular niche. In campaigns with straightforward villains to whom intrigue isn’t important—that is, if your campaign is more Infinity War than James Bond—then this features won’t do you much good. Creative rogues may be able to squeeze some use out of them, but these features really rely on your Dungeon Master setting the stage for them to be useful.

You may be able to ask your DM to involve elements of intrigue that suit your subclass. Howeveryou’re your DM is unwilling to bend their campaign arc, or if you like assassinating enemies but just aren’t that interested in subterfuge, then you may want to multiclass. Rogues uninterested in making false identies often choose to multiclass after reaching 8th level in the rogue class, before they gain their 9th-level subclass feature. Good potential multiclassing options include fighter (both Champion and Battle Master are useful), monk (particularly if you want to follow the Way of Shadows), or—if you want to make a more unusual choice—cleric (following a domain like Knowledge or Trickery) or sorcerer (with the Shadow Magic bloodline from Xanathar’s Guide to Everything) can be exciting choices.  

Suggested Build

Like most classes in D&D, the rogue doesn’t choose their subclass until 3rd level. If you’re playing a rogue from 1st level and think you want to become an Assassin later, you should choose a race that improves your Dexterity score. If you plan on creating false identities, then consider making Charisma your next-best feature. If you’re uninterested in subterfuge and would prefer assassinating monsters in dungeons, making either Intelligence (to improve your Investigation abilities) or Wisdom (to improve your Perception abilities) your second-highest ability score would be wise.

Wood elves, dark elves, and lightfoot halflings make excellent assassins, thanks to their bonuses to both Dexterity and Wisdom, and because they have racial traits that make it easy for them to hide in plain sight. Forest gnomes make surprisingly good assassins, thanks to their bonuses to both Dexterity and Intelligence, and their ability to cast minor illusion at will. Half-elves can be suave and charismatic assassins, and humans are flexible people who can adapt to just about any calling—especially if you play a variant human with the Skulker feat.

As usual, your character’s background is up to you. You can come up with all sorts of interesting stories and oddball characters by pairing unlikely backgrounds with the Assassin archetype. Are you a personable and charming assassin, who prefers to observe opponents over a game of Three-Dragon Ante while sipping a shaken-not-stirred martini? The Folk Hero or Charlatan backgrounds would serve you well. Or are you a silent and stoic killer, bred by war or wilderness? The Soldier or Outlander backgrounds might fit you.

It’s a safe bet to choose EQUIPMENT when given the choice between GOLD or EQUIPMENT during character creation. As long as you have a weapon with the Finesse trait (such as a rapier, short sword, or dagger), you practically have a license to kill. Daggers may not deal a lot of damage, but their small size allows them to be easily concealed. This is much more useful than a few extra points of damage—especially since your Sneak Attack and Assassinate features are really where your damage will be coming from, not your weapon’s innate damage die. If you plan on infiltrating residences, then a burglars’ pack will help you. Otherwise, choose a dungeoneer’s pack.

Feats

At 4th level, you get to gain either an Ability Score Increase or a feat. Choosing an Ability Score Increase lets you increase one ability score by +2 (such as increasing your Dexterity score from 16 to 18) or increase two ability scores by +1 (like increasing your Dexterity from 15 to 16 and your Wisdom score from 13 to 14). Increasing your ability scores makes you better at a wide variety of things; for instance, increasing your Dexterity score makes it easier to hit with your weapon attacks, and it also makes it harder for enemies to hit you, while also making you more likely to succeed on Dexterity saving throws and make successful Dexterity checks.

Feats, on the other hand, give you a special ability that could be more helpful in a specific circumstance, as opposed to the broad improvement that an Ability Score Increase could give you. Dexterity is your most important ability score, since it governs your ability to hit with attacks. Once you’ve increased your Dexterity score to 20 (its maximum value), or even just to 18 (a pretty good value), you may want to choose a feat. You can choose any feat you want to support your character concept, but there are some feats that may be more useful to your character than others.

Alert. You are a character that loves to go first in combat, since your Assassinate feature gives you advantage on attacks against creatures that haven’t acted yet.

Actor. If you don’t want to invest too much in Charisma, this gives you some very specific abilities that complement your suite of social impersonation features.

Inspiring Leader. An odd choice, but if you’ve invested in your Charisma score, this is a good way to be more of a team player by inspiring your party.

Sentinel. Don’t forget, you get one use of Sneak Attack per turn—not per round, per turn. This means you can Sneak Attack on your turn, and then use your reaction on an enemy’s turn to attack again, potentially getting Sneak Attack. This is most useful when you coordinate with your allies to ensure that they’re always in position to help you get Sneak Attack.

Sharpshooter. If you want to assassinate your targets from range (and really, why wouldn’t you?), this feat cranks your already incredible damage output up to 11. Take care with this, though. Since you only have one attack per turn, sometimes you just want to hit in order to activate your Sneak Attack damage. Taking a –5 penalty to hit and then missing isn’t always worth the potential to gain an extra +10 damage.

Skulker. Being able to shoot without giving away your position is incredibly useful. The other benefits are nice, too.
