Whats the best gems for a blade dancer that is focusing on mainly attack.

Amethyst - # Additional Dmg on Crit Hit (also a life drain version), Sapphire - # Sec. Movement Speed Reduction and # Additional Dmg When Enemy Blocks/Evades (also straight additional dmg without move speed), Citrine - # Additional Dmg When Enemy is Stunned or Knocked Down, Ruby - # Additional Dmg is Triggered on Attack (also stuns for # sec and inflicts # additional dmg - triggered on attack).

I think those would be pretty decent, as the shape changes from Triangular -> Square -> Etc the # increase changes with the Hexagonal being the best atm.

Everything that I've seen is has shown Ruby, Citrine, Amethyst as your primaries to start. Add. damage Diamond if you can get your hands on one as well.
