Dragonblade said:You could target the Force Orb at the ground. Effectively you give up your primary damage in order to have a better chance at doing secondary damage.
And of course, you're setting up a precedent for other powers to do the same thing. Thats potentially quite unbalancing. Stretching a non-AoE attack into one is an abuse of the rules, and its quite possible to break the game with it.
By similar logic, you could target a door with otiluke's resilient sphere to block access to a room.
