Stabilize spell? Why does it have a DC?

[MythTrip]

In spell description it says anyone under -1 health no longer keeps dying and is automatically stabilized. So why does it have a DC? What does the DC refer to? thank you!!

All spells have a DC. The DC is 10+spell level+ the casting stat (Int/Wis/Cha bonus depending on the caster type) and any additional bonuses from feats or magic items.

However, spells that you cast on allies are never rolled against in Kingmaker/WotR. It is a holdover from tabletop where there are a few, rare examples when characters are forced to roll to resist even friendly spells or when a player might decide his character doesn't want someone to cast a spell on them and rolls to resist.
