Great build. I wonder if the ring "Sunwalkers Gift" would stack with natural dark vision (prolly not). I'd like to make the same build with a wood elf. That way you'd get extra movement, free proficiency with a longbow and the ability to achieve 20 dex (17 creation, +2 at lvl 4 and +1 from Auntie's hair).
As it turns out Sunwalkers gift doesn't stack.
Last I had heard auntie's hair only gave you +1 str, but maybe they fixed it.
if you take the +2 dex feat you lose the Weapon Master feat and won't be able to grab proficiency with Heavy Crossbows, Longbows and Scimitars. Also Drow get the hand Crossbow feat for free - and you can now dual wield hand crossbows and there is even an enchanted HAND Crossbow!
Also Wood Elves only get regular 12m range Darkvision and Drow get 24m range Superior Darkvision. Ranged weapons are all 18m.
Pew pew pew!
Figured ring didn't stack, the ring of poison resistance on a dwarf doesn't stack
There is a dialogue path with Auntie that allows you to pick your stats reward (maybe bugged because I picked Cha and got a Cha & a Str hair)
Wood Elves get longbow & shortswords + more movement = more mobility
20 dex is + 1 to hit & +1 dam over the drow 18 dex build, that makes up the average damage difference between the heavy crossbow and the longbow with a +5% better chance to hit
No getting around the extra range you can shoot obscured targets without penalty, well kinda. I have Shadowheart cast the light cantrip on my tanks weapon so at least near them no one is obscured.
1) Longbow is 1D8/ Heavy Crossbow is 1d10 - so you lose +2 damage range.
2) You also get scimitars as an additional martial weapon, which given that you can make two adamantine scimitars in the forge is a huge deal.
3) The Giantbreaker Crossbow is amazing, and is a Heavy Crossbow, so you lose out on that magnificent weapon as well.
4) The extra movement from wood elf is great, but given that Rogues have dash as BA and an extra BA it's kind of like putting a hat on a hat. I don't even bother with boots of speed and the crusher ring because I have never had a problem being where I need to be. 1.5 meters movement range versus being able to sneak attack someone from an additional 6m range is a no brainer. In the Underdark especially you are going to get value out of that extra distance, and the Grymforge as well which is a highly vertical and dark location.
5) Finally the hair off auntie is confirmed still bugged. So the best you could do is 19 dex which is the same as 18 dex really.
