This mod reduces the effectiveness of psychic powers in combat. It's simple, they each now require one action to be spent on concentrating first. Changing modes (switching from telekinesis to heat point, for example) also causes the psychic to refocus and spend an action concentrating, as does switching targets. The stronger version of this mod (James Randi Doesn't Have Time for Your Crap Hack) increases the concentration time to a full round.

This isn't an official addition or change to the Midian game. Rules hacks/mods are optional rule tweaks that a troupe may implement in their own games. Mostly though, they are playing around with game mechanics for the sake of doing so.
