Other than something short & ugly, what do you envision a Halfling/half-orc pairing would produce?
Because the session that kicked off my All Barbarian game was the 1/2orcs being summoned (via a Horn of Vallhalla) into a wild party full of well, sex drugs & rock&roll IS the best description, hosted by a bunch of satyrs.
Dice were rolled, cards were drawn, & one of the 1/2orcs ended up with the Halfling serving girl behind the bar....
Halfling/ half orc. Interesting combination. Using the basic framework I have, the stats would depend on the primary source. Have not yet gotten into Dominant genes and might not. Much funner to let the players pick.
Half-orc/Halfling
Half-orc subrace: Half-Hin
+1 dex (replaces your +1 constitution), choose lucky or brave
Halfling subrace: Quarter-orc, Quarter-Human (AKA Half-half-orc)
+1 Strength, choose Menacing or Relentless endurance
Maybe it is a bit lazy to make them so basic, what do you think? Of course, if I (and anyone who wants to use them, feel free) treat these as a basic framework, and stacks on whatever they feel works, I am sure they will come out plenty fleshy, mechanics wise.
One issue might be that there are some choices that are obviously better from a mechanics perspective, and I am not sure how to balance that kind of thing off. My players are not power-gamey enough to see these options and choose one for pure mechanical benefit, so I have no experience in the area.
