Can you hold a 2H (not 1+, actual 2H)weapon and cast spells that have the Somatic component?
The text of somatic components seems to imply you can:
A somatic component is a specific hand movement or gesture that generates a magical nexus. The spell gains the manipulate trait and requires you to make gestures. You can use this component while holding something in your hand, but not if you are restrained or otherwise unable to gesture freely.
but the Interact action seems to imply that any changing of hand placement is an Action.
So do I cast while holding my polearm normally? Do I have to pay an Action to take my hand off the weapon? How about to put it back on the weapon?
Do we have a definitive answer for this? I tried searching but failed miserably.
