What is the difference between Shapechange and true polymorph?

Shapechange doesn’t let you turn into anything with class levels, but True Polymorph doesn’t have that limitation, so long as the new form + class levels doesn’t push the CR over your level. This is an excellent explanation!

Can PCs get legendary actions?
