I watched a video from Dungeon Dudes on YouTube where they rated the Ranger subclasses. Around the 23:18 mark, they mentioned that the new Beast Master’s Primal Companion feature from Tasha’s Cauldron of Everything can allow the Ranger to forgo one of their attacks to allow the Beast to take the Attack action, on top of the action that they can make using the Ranger’s bonus action. The Primal Companion feature description says the following:
In combat the beast acts during your turn. It can move and use its reaction on its own, but the only action it takes is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. You can also sacrifice one of your attacks when you take the Attack action to command the beast to take the Attack action. If you are incapacitated, the beast can take any action of its choice, not just Dodge.
As far as I know, a creature can only take one action on their turn. Is this a specific ruling for the Primal Companion since it doesn’t have its own turn because “it acts on your [the Ranger’s] turn?” Also does this mean that the Ranger can break up their movement, actions, and bonus actions with the Beast’s on their turn, essentially controlling two characters freely? In the video, Monty mentioned that a level 11 Beast Master Ranger can make one attack and have the beast attack four times which is crazy in my opinion.
