Healing Word casting time is 1 bonus action. My daughter is playing a lvl 2 Bard and has this spell. I noticed that it takes a bonus action in order to cast... the problem I'm having is I don't see anything under the Bard class at 2nd lvl that grants a bonus action... is this spell not usable as a 2nd lvl Bard? Thanks in advance!
Every character has an Action, Movement, Bonus Action, and Reaction each round. However, a Bonus Action is something you can only do if you have a spell or feature that uses a bonus action, you can't just choose to do it.
So she does not need any special feature to allow her to cast spells with a casting time of one Bonus Action that are available to her class. :) The fact that it has a casting time of 1 bonus action is what allows her to use her bonus action that way.
Just remember that if she casts a leveled spell with a casting time of a bonus action, she can't use her action to cast another leveled spell (though she could cast a cantrip)
