How much damage does Oliathus's hellfire orb do, and why is it fire/necrotic in the book(and in most of the sources I have checked) and slashing / necrotic in the damage block? I suspect it was simply a weird error that happened, but I just wanted to keep y'all updated on the weird stuff.
ATTACK :
<span class="inlinerollresult showtip tipsy-n-right fullcrit" title=" Rolling 1d20+(11+0) = ( 20 )+(11+0)">31 | 30 (I totally critted this!)
(To GM):
DAMAGE:
13 + 9 slashing

The death knight hurls a
magical ball of fire that explodes at a point it can see within 120 feet
of it. Each creature in a 20-foot-radius sphere centered on that point
must make a DC 18 Dexterity saving throw. The sphere spreads around
corners. A creature takes 35 (10d6) fire damage and 35 (10d6) necrotic
damage on a failed save, or half as much damage on a successful one.
