Orc Blood: For all
special abilities and effects, a half-
orc is considered as an
orc. Half-orcs, for example, are just as susceptible to special effects that affect orcs as their orcish ancestors are, and they can use magic items that are only usable by orcs.
Darkvision: Half-orcs can see in the dark up to 60 feet.
Darkvision is black and white only, but it is otherwise like normal sight, and
drow can function with no light at all.
