I tried to make a DPS Chanter and it's working pretty good so far on Hard mode.
It's a Hearth Orlan, mainly because of their racial, where a normal hit can turn into a crit if you attack the same target as an ally. Maxed Might and Int, dropped his Perception as low as I could and put it into Dex for the faster action. He is using a Spear so he can stay behind the Fighter, but still provide support with his Chants.
You could pick Dwarf and get up to 21 Might at the cost of Dex I guess. The reason why I didn't pick Dwarf is because I can't have my main character as one, I just can't. Thinking about it tho, maybe Orlan isn't the best choice for a DPS Chanter, but hey.
Sure he doesn't have the splash as a Barb or the expertise of a Fighter, but he is a buffbot/caster afterall. I like it, even tho it's not min/maxed I guess, haven't played enough for that sort of thing.
Stats:
18 Might
10 Con
17 Dex
5 Per
18 Int
10 Res
If anybody have a better build/suggestion I am open for criticism. I am not a pro builder or anything like that and still new to the PoE system.
I still think Tank Chanter is better to do, because their accuracy is only average, while their deflection is Very High.
