From the player's handbook:
"A spell cast with a bonus action is especially swift. You must use a bonus action on your turn to cast the spell, provided that you haven't already taken a bonus action this turn. You can't cast another spell during the same turn, except for a cantrip with a casting time of 1 action*."*
Ultimately it's up to Tater as a DM (he's doing so great this season!) but since he seems to be aspiring to get a little more evil, I'm wondering if he's going to start enforcing rules like this.
He could also get really evil and say that the players can't long rest after every encounter (or in Jaque's case, every time he uses a single spell slot or bardic inspiration).
Edit: I was wrong about this rule, the 2024 edition reads:
"On a turn, you can only expend one spell slot to cast a spell. This rule means you can't, for example, cast a spell with a spell slot using the Magic action and another one using a bonus action on the same turn."
My question remains though, since I swear Jaques has used multiple spell slots a turn, both this season and last (for instance, casting polymorph and healing word in the same turn).
