Wait if group D is whatever you wish doesn't that spread out the monster races. Group D would be for things like up coming approved classes (Artificer comes to mind) and the spot where you ask the DM can I play a gensai? or use a feat from this module? etc.
-Player has portfolio of three characters.
-Character A is either: Fighter, Barbarian, Monk, Rogue
-Character B is either: Ranger, Paladin, Bard, Warlock
-Character C is either: Cleric, Druid, Sorcerer, Wizard
Races: from the PHB
Abilities would be Point buy @ 29pts
HP: Max @ 1st lv - average after that
Max starting gold for class (i.e. a monk would have 20gp, a bard would have 200gp to spend)
Backgrounds - 2 backgrounds should be from the PHB the third may be PHB or SCAG
Then there is Group D:
Race: PHB or chose from list
Aasimar: Protector, Scourge, Fallen (DMG (base only), VOLO)
Deep Gnome/Svirfneblin (EE, SCAG)
Dwarf: Duergar (SCAG)
Genasi (PotA, EE)
Goliath (EE, VOLO)
Halfling: Ghostwise (SCAG)
Half-Elf: Variant (SCAG)
Tiefling: Variant (other than Winged) (SCAG)
Class: Any - discussed with DM other players for balance
Abilities: Array - 15, 14, 13, 12, 10, 8
HP: Max @ lvl 1 - average after that
Starting Equipment based of quick build for class/background
Special: Feats, equipment, and such open to discussion, so this character could just be a regular human fighter but the feats are out of some new book or something which makes him fit into Group D
I think we may be getting there. So much closer than before thanks hafrogman
Just curious why you're going 29 point build (straying from RAW 27)?
Also, I'm not sure limiting the Backgrounds is a good idea, since per RAW you can create your own background. Many of the SCAG backgrounds are even just that: retooled versions of the PHB ones (as far as ideals, bonds, flaws, personality go). Basically just use the Custom Background template and make sure any Feature that isn't from the book gets approved by the DMs.
