"Casting TimeIs there a limit on the number of spells you can cast on
your turn? There’s no rule that says you can cast only X
number of spells on your turn, but there are some practical
limits. The main limiting factor is your action. Most spells
require an action to cast, and unless you use a feature like
the fighter’s Action Surge, you have only one action on
your turn.
If you cast a spell, such as healing word, with a bonus
action, you can cast another spell with your action, but that
other spell must be a cantrip. Keep in mind that this particular limit is specific to spells that use a bonus action. For
instance, if you cast a second spell using Action Surge, you
aren’t limited to casting a cantrip with it.
Does the rule on casting a bonus action spell apply
when you take a bonus action granted by a spell? The
rule on casting a spell as a bonus action (see PH, 202)
applies only on the turn you cast the spell. For example,
spiritual weapon can be cast as a bonus action, and it lasts
for 1 minute. On the turn you cast it, you can’t cast another
spell before or after it, unless that spell is a cantrip with
a casting time of 1 action. Until spiritual weapon ends, it
gives you the option of controlling its spectral weapon as a
bonus action. That bonus action does not involve casting a
spell, despite the fact that it’s granted by a spell, so you can
control the weapon and cast whatever spell you like on the
same turn.
Can you cast a reaction spell on your turn? You sure can!
Here’s a common way for it to happen: Cornelius the wizard
is casting fireball on his turn, and his foe casts counterspell
on him. Cornelius also has counterspell prepared, so he
uses his reaction to cast it and break his foe’s counterspell
before it can stop fireball."
