Gloom Stalker / Assassin: sick multiclass?

Posted by Tobi Tarwater on Sunday, July 14, 2024
(My apologies if this has been well discussed before. Somebody asked for help with this build, but the math wasn't discussed.)

Gloom Stalker: 5
Assassin: 3
Using Hunter's Mark

Does this (potentially) do as much first-round damage as I think? Let's talk the best case, that your opponent is surprised:

Melee:
Two weapon fighting
2 Attacks (Ranger 5), plus offhand.
One more attack, that does an extra +1d8, from Dread Ambush
(If I were doing this I'd probably go variant Human and take Alert feat, for a total Initiative bonus of +11)

Let's say we're using shortswords because I hate rapiers
So that's 4 attacks doing 2d6 each (weapon plus Hunter's Mark), + 1d8 + 2d6 Sneak attack, all doubled, plus 4xAbility, which would be +4 at this point.
So 20d6 + 2d8 + 16 = (avg) 95, max of 152

Alternately, a bow build with Sharpshooter (variant Human) would get one less attack but do +10 on each attack. That would be:

3 attacks doing 1d6 + 1d6 Hunter's Mark, plus 1d8 for Dread Ambusher, plus 2d6 Sneak Attack, all doubled, plus 3 * 10 for Sharpshooter, plus 3 * 4 for ability bonus = 16d6 + 2d8 + 30 + 12 = 107 (avg). However, the -5 penalty with Sharpshooter means more misses.

Either way that seems like a pretty sick opening round from a level 8 character, without any magic items or buffs.

Thoughts?

EDIT: Not really relevant, but if I actually did this I think my next six levels would Shadow Monk. Super fun to BAMF! in and wreak havoc.
