@Cu Chulainn The varient D&D 5e rules are closer to the
Pathfinder rules, where instead of getting +1 to all ability scores as with the standard D&D 5e racial rule you get +2 to one ability score
(although in D&D 5e this can be split between two abilities if you want, giving +1 each), an additional skill proficiency and a feat.
EDIT: Actually, checking the exact wording of D&D 5e ("Ability Score Increase. Two different ability scores of your choice increase by 1." - Player's Handbook, page 31) means you have to take the +1 for separate abilities, unlike Pathfinder where you take +2 for one ability.
Luckily when I made Noxolo with D&D 5e I used the varient rules, which gave her a skill
(not sure which one I went with for this bonus, might be her Acrobatics) and the War Caster feat, but since her ability rolls were relatively low the +2 ability bonus still leaves her short of the 20pts buy.
