Congrats again on LVL 2- couple things before you make your adjustments.
First and most important is this will kind of be like a video game level up. You get your new HP added to whatever your current total is. You get the HD to spend if you wish. And for the spell casters you get another first level spell slot, but not the extra spell (prepared spells only).
So Barakas is at 4/12 HP right now. And I think both Terry and Niklos cast one spell so they will have 2/3 1st lvl spell slots if they take a level in a spellcasting class.
Which brings me to the second thing. Forgot the randomness of all this, but tglassy already rolled so here are the other classes if anyone wishes to multi-class.
Cyan:
1) Barbarian
2) Fighter
Niklos:
1) Druid
2) Fighter
3) Monk
4) Ranger
5) Rogue
Talinthos:
1) Bard
2) Fighter
3) Sorcerer
4) Warlock
Terry:
1) Bard
2) Druid
3) Sorcerer
4) Warlock
I said before that the rogues had to wait till level 4 but I will ex-nay that because of the rule to keep each class wtihin 1 lvl of each other. I think you get to chose the path/archetype to fit your first class.
I was looking at Cyan as she seems to be the frontline warrior for the group and could benefit from this. And if jumcchiello was thinking of another class for Terry her options look like added support roles if your thinking of that route. I looked up divine soul for sorcerer and thought it a great RP option.
Niklos gains preserve life a great use for his channeling ability I would take another level of cleric. But just my suggestion not writin in stone.
Only thing I thought cool for Talin was to roll warlock and then go hexblade. Cool combo.
So that is my short observation, please use the above as you decide on your lvl up. And Congrats again - a well earned lvl.
