This is still Spoiler Territory, some people maybe want to discover this on thier own, pls be kind about the way on how to unlock these characters.
In this game a progeny mechanic exists, this means 2 characters can have a child together, this is indicated during camping with people either having 3 or 4 hearts with eachother.
3 Hearts indicates, that they can become realy good friends, but nothing more.
4 Hearts indicates, that they can become Soulmates, wich after reaching 4 hearts during camping unlocks the 4 ??? classes or the progenys (variant classes)
Getting 4 Hearts can rough sometimes, but it can be done as early as Area 2 if you focus on the relationship between 2 Characters.
Below this is a list with the Couples wich unlock the class:
- Varangian (Pox) Archon + Valkyrie
- Juggernaut (Aia) Aegis + Enforcer
- Spectre (Nava) Empath + Marksman
- Gunslinger (Sidara) Commando + Sabotuer
