Was totally unaware of these restrictions. Thanks for pointing them out.
Larian were saying that they wanted to remove multiclassing restrictions, so I assume those might or might not make it into the final game. But knowing them, they might get rid of the rule.
Almost a safe bet I'd say.
Yeah, I would definitely gloom 5 before assassin. If you want the skills fast do 1/1/1 and then make a call on whether you want to shoot more or support more and do gloom to 5 or cleric 3 or 4 based on that choice.
RP wise I'm thinking of someone strongly rooted in religion who at some point is approached by the church/gets a call from her deity to execute certain "special assignments", a spy of the Vatican kind of character (hopefully it's not going to clash with Shadowhearts origin story). Anyway, for that reason she starts off as Cleric:
Cleric(Thievery) 4/ Ranger(Gloom) 3/ Rogue(Assassin) 3
I am leaving the last 2 level open. Maybe she will be coming back to church (Cleric 2), maybe she becomes the perfect killer (Gloom 2), maybe she pursues power in general at the end (Gloom 1 / Assasin 1 for all three ASI). Who knows?
