Gloom Stalker Assassin Multiclass Level Selections
Gloom Stalker Assassins are all about using their Stealth to Hide and trigger hugely effective Surprise Rounds with Sneak Attack (often Ranged) on the opening turn of combat.The Best Gloom Stalker Assassin Build combines six levels of Ranger, four levels of Rogue, and two levels of Fighter.
While many builds utilize an even split of Ranger and Rogue for six levels each, neither Rogue nor Rager learns any absolutely crucial skills or Features at these end levels with this split, so you’re able to gain much more value in exchanging them for two levels in Fighter. This lets you gain Action Surge and Second Wind, which will allow you to have significantly more impact upon your opening ‘ambush’ round in battle.

Upon creating your character, you’ll want to take your first five levels in the Ranger Class.
AtLevel 1, You’ll need to select aFavored EnemyandNatural Explorer Environment.For your Favored Enemy, choose Bounty Hunter. As a result, you will gain Proficiency in Investigation, and creatures that you hit with Ensnaring Strike have Disadvantage on their Saving Throw.For your Natural Explorer Environment, choose Ubran Tracker. This will grant you Proficiency in Sleight of Hand, which will further enhance the strength you have in this Skill due to your high DEX.

At Level 2, select Archery as your Fighting Style. This will add a +2 bonus to Ranged Weapon Attacks, which works hand in hand with your Ranged Sneak Attack ambushes to hit targets with higher AC.
AtLevel 3, it’s time to select your Subclass. Of course, you’re going to need togo ahead and choose Gloom Stalker. At Level 3, this will grant you +3 Initiative, Superior Darkvision (24m), Hide as a Bonus Action (Dread Ambusher),the Disguise Self Spell, and Invisibility through Umbral Shroud. You will also gain the bonus of +3m Movement Speed and an additional attack that deals +1d8 damage on your first turn of combat.

AtLevel 4, you will be able to select your firstFeat, so go ahead and chooseSharpshooter.This Feat amplifies your lethality with your Ranged Attacks by removing penalties from High Ground Rules. Additionally, your Ranged Attacks will have a -5 penalty to Attack Rolls, but deal an additional +10 damage on a hit.
As you have a high DEX modifier, you’re already very likely to hit your Ranged Attack shots, and the ability to give yourself Advantage with Sneak Attack (once the Rogue class is added) every round through the Hide Bonus Action means that you’re much more likely to reap the benefits of Sharpshooter, with much fewer consequences from the penalty.
AtLevel 5, you will receive your Extra Attack, which allows you to make two Ranged Attacks per Action instead of one. This is hugely effective for stacking damage with Sneak Attack and Sharphooter, and you’ll likely notice the benefits almost immediately in combat.
Now that you’ve taken your initial five levels in Ranger and set yourself up with Extra Attack,it’s time to dip into the Rogue Class for the next three levelsto grant yourself the benefits of the Assassin Subclass and create that Stealth-oriented synergy that makes the Gloom Stalker Assasin so viable.
AtLevel 1, you will need to select yourRogue Expertise Skills. SelectStealthas your first choice, as the Gloom Stalker Assassin is centered around hiding and ambushing. For the second choice, you can choose betweenSleight of HandandPerception. If you want your character to be a reliable Lockpicker and potential pickpocket, thenSleight of Handis the way to go. If you’d rather have your character focus on scouting and identifying traps or hidden items in the environment, thenPerceptionwill suit your build better.
AtLevel 3, you will finally be able to select your Rogue Subclass, so go ahead and selectAssassin. This is where the fun really starts to take off with this build thanks to Cunning Actions plus the bonus Advantage and extra damage from Sneak Attack.
Now that you’ve set up with the Gloom Stalker and Assassin Classes,it’s time to take two levels in the Fighter Class. This will result in even more utility for your character due toAction Surge, which will let you Attack up to four times during one round of combat, andSecond Wind, which enables you to heal yourself in a pinch without needing to rely on your main healer. Action Surge also stacks with the Gloom Stalkers bonus attack on the opening round of combat, enabling you to Attack up to six times – which is devastating in terms of damage output.
Note that Second Wind and Action Surge can only be used once per Short Rest, so you’ll need to be clever about utilizing your Rests between combat to refresh these abilities, due to the immense value they bring.
Now you’ll need toadd your next level in Rogue once again, bringing you up to Level 11 (5 Ranger, 2 Fighter, 4 Rogue). At this point, you’ll be able to choose another Feat, so selectAbility Increase, andadd +2 to Dexterity. This will bring your DEX up to 19, amplifying your success in Stealth, Lockpicking, pickpocketing, and Attack Rolls even further.
Lastly, take one last level of Ranger to complete your build. For yourFavored Enemy, selectMage Breaker. This will grant you Proficiency in Arcana and the ability to cast True Strike, which is another method for granting yourself Advantage against a target for huge damage with Sharpshooter.
For yourNatural Explorer, that choice is up to your preference. If you’d like the benefits ofFind Familiarfor causing distractions for pickpocketing or inducing status effects on your enemy for battle, then selectBeast Tamer. Otherwise, you can choose one of theWasteland Wandereroptions to grant yourself Resistance to Cold, Fire, or Poison damage.
