ABILITY SCORE INCREASES FROM ELSEWHERE
Since 2014, characters have received ability score
increases from several sources, either from a Race
that has the Ability Score Increase trait or from
the ability score rules in Tasha’s Cauldron of
Everything, Monsters of the Multiverse, and other
books. If you make a character using one of those
older sources and get ability score increases from
it, the character doesn’t also get ability score
increases from Background, unless you forgo the
older ability score increases to gain the increases
from the Background rules here.
