I'm trying to help out one of my players optimize his character. His desired path is the Unofficial Drizzt Do'Urden build but tweaked it a little according to his taste by going
Fighter 1 > Barb 1 > Barb 2 > Fighter 2 >Ranger 1> Ranger 2> Fighter maxed.
He is a Human variant Dual-wielder using 2 Rapiers with Str, Dex, and Con maxed out at 1st-level and he plans on a Strength-maxed build with his future ability score increases.
He is getting Barb 2 for Reckless Attack which states:
... you can decide to attack recklessly. Doing so gives you advantage on melee weapon attack rolls using Strength during this turn...
During our discussion, we came up with a way for him to not need the 2 ranger levels to get Hunter's Mark and the concentration needed by it (since he will be facing challenges in melee). That was to get 1 level of Rogue for Sneak Attack. We decided not to go for it but it still left a question in mind since Sneak Attack states:
...Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or ranged weapon...
Now, my question is, given that Reckless Attack only gives advantage if you use strength, and Sneak Attack requires only a finesse weapon or ranged, it doesn't say you have to use Dexterity:
Can Reckless Attack activate Sneak Attack?
