DEX barbarian 5e?

[GalacticAxekick]

The Barbarian already benefits immensely from Dexterity.

• Proficiency with all finesse weapons
• Dex and Con bonuses to AC
• Advantage on most Dex saves
• Advantage on initiative rolls

The only reasons to use Strength, as a Barbarian, are (1) to deal Rage Damage and (2) to use Reckless Attack. The simplest way to write a Dex Barbarian would be to get rid of those two reasons:

Tracelike Fury. Starting at 3rd level, your rage is a state of focus that allows you to strike vital targets with great precision, even if that means putting yourself at risk. You can use Reckless attack when you make any attack using Dexterity, and you can deal Rage Damage when you hit a creature with any attack using Dexterity.

Patience & Precision Starting at 6th level, you gain proficiency in two of the following skills: Acrobatics, Sleight of Hand, or Stealth. If you choose a skill that you are already proficient in, you gain expertise instead.

Cat & Mouse. Starting at 10th level, you can Hide or Search as a bonus action.

Zero to One-Hundred. Starting at 14th level, if you are not surprised at the beginning of combat and aren’t incapacitated, you can begin combat with a surprise round, but only if you enter your rage before doing anything else in that round.

Stoic Champion. When you gain the Primal Champion feature at 20th level, you can increase your Dexterity score by 4 instead of your Strength score.
