The achievement Group Hug reads
Raised a Hero of each type to Level 70. After the game released on Steam, they released the New Heroes DLC, which gives you access to gender-swapped versions of the original 4 classes who have different activated abilities.
This is a table showing which of the New Heroes are equivalent to the originals:
Original New Heroes DLC Squire Countess Monk Initiate Apprentice Adept Huntress Hunter
With that in mind, I need to know if I only get Group Hug for leveling the original 4 classes to 70, or can I mix and match for example, a Squire, Initiate, Apprentice and Huntress and still get the achievement? Or would I have to use all 4 from either the original group or the New Heroes DLC, by which I mean either leveling the Squire/Monk/Apprentice/Huntress or Countess/Initiate/Adept/Hunter together?
