Hi, I'm making my first Pathfinder character, and I'm considering DEX Urban Barbarian with a scimitar. I'm thinking Hobgoblin, Goblin or Human, and one consideration is how fast can I get the Dervish Dance https://www.d20pfsrd.com/feats/combat-feats/dervish-dance-combat/ .
In Particular I don't understand how the requirement for 2 ranks in Perform(Dance) works.
For example as a human with 15 point buy I can go:
STR/DEX/CON/INT/WIS/CHA
10/18+2/16/7/7/7
+2 DEX is from human racial ability
Then I have 4 skill points to distribute but Perform is at -2 initially. What does it mean in the requirements that I have to have 2 ranks in Perform(Dance)? Does it mean the total skill should be +2? Or just that I need to spend to skill points on Perform(Dance)?
Can I spend many skill points on Perform(Dance) at once (on the first level)? Or do I have to do it 1 by 1?
Ideally I would add 4 skill points to Perform(Dance) on the first level and get it to +2, and get Weapon Finesse and Dervish Dance as my feats. Can I do that?
If no, then it doesn't make sense to go Human, because there's no good feat that I need to get early, so I probably should go for Hobgoblin
STR/DEX/CON/INT/WIS/CHA
10/18+2/16+2/7/7/7
Or maybe even Goblin for +4 DEX (but then my damage dices are lower and that kinda sucks for a barbarian :) ).
Another consideration is taking Brawler as a Rage Power at level 2 - if I understand correctly I can then do 2 attacks each round - once with the Scimitar and one unarmed strike (which also benefits from Weapon Finesse). But I'm not sure if that's correct. Can Urban Barbarian even get Brawler as a Rage Power?
Any ideas how to optimize this?
