Domain Spells are spells that a cleric or wizard can prepare and cast using their spell slots. This means that Domain Spells do not use spell points, and are not limited by the number of spell slots a caster has.
This can be a major advantage for casters who want to prepare a large number of Domain Spells.
However, there are some caveats to this. First, Domain Spells that deal damage may have a reduced effect if cast using too many of a caster’s available spell slots.
Second, some Domain Spells, such as those that summon creatures or affect the environment, may require more than one spell slot to cast effectively.
