Some spells like Investiture of Flame, Investiture of Ice, Investiture of Wind, Investiture of Stone and Dragon's Breath have effects that grant a damaging spell-like action. Is it possible to cast the spell on yourself and maintain concentration, then enter Wild Shape and use those actions?
I'm aware that there are probably many more spells like these that grant actions, and some, like Dragon's Breath, would need a multi-class. I picture a tiny spider throwing tornadoes or causing earthquakes or spewing fire.
I'm also aware that it was unofficially tweeted that a dragonborn can still use their racial Breath Weapon trait in Wild Shape.
