Heretic of The Seventh Circle
Okay, but that has no impact whatsoever on the point of my reply.Doc, I don’t believe this is correct. A tiny cannon can be held in a hand, but does not have to be. Either a small or tiny cannon can have legs.
Snippets from the subclass:
can take an action to magically create a Small or Tiny eldritch cannon in an unoccupied space on a horizontal surface within 5 feet of you. A Small eldritch cannon occupies its space, and a Tiny one can be held in one hand.
When you create the cannon, you determine its appearance and whether it has legs.
