- Do you guys do this ? Or is it best to follow the default setup ?
Elective Mode allows players to really customize their builds, and I definitely recommend it for anyone looking who likes to test a variety of skills.
2. ) So if you follow this custom button layout , what do you look for in terms of skills and rules ? What does the most damage ? I have just learned the seven strike does a lot and it looks awesome.
In the same menu that you turned on Elective Mode there is another option called Show Advanced Tooltips further down. I also recommend turning this on to get more information about your skills, so that you can make more informed decisions about what skills to use. After that, just play around till you find something you like! Sometimes you'll find Legendary items that change the way skills work, and will make you want to try a whole different set up.
3.) Is there a an all black armor for the monk late game ? Or can you change the color of the armor ?
You can dye your armors, and the one you want to keep an eye out for is called Abyssal Black Dye. To find it just keep an eye on what dye the vendor offers (there is a dye vendor in every Act) and buy up a bunch of them when you find it for sale.
4.) What stats to look for in monk items? dexterity or both dexterity and vitality ? Why is it when I use a staff the attack animation is pretty slow compared to the fist weapons ?
As iamcuddles pointed out, generally you'll want to find items with Dexterity and Vitality, but you'll get even more specialized as time goes on, and you test what works and what doesn't. 2-handers are generally slower than 1-handed weapons, but if you keep an eye on each weapons Attack Speed you'll eventually get a better feel for the speed you like.
5.) What is the advantage of the blacksmith items? I have leveled them up so far but I think some legendary items are better.
Items crafted by the Blacksmith can be very useful, but each item should be judged on its own. However, there is a point where the Legendary items you find while adventuring will be generally better than what the Blacksmith can give you, with a few exceptions.
6.) The mystic ally, is it useless ? If you cast mystic ally then use another button assigned to it, will it still be there? What's his health
The Mystic Ally isn't useless, but it's definitely a question of player preference. It is a skill, though, so swapping it out with another skill will remove the ally.
