You know, I've never noticed that before. We've always played strain as lucidity damage (we've only ever had one async). I think I like the idea that it does mental stress more, but it should be easy enough to use physical stress instead. In fact I think that makes it more balanced so a character can't just mark off a bunch of mental stress to boost combat rolls while soaking damage with the physical stress. Now it's riskier because your easier to take out if you use too much Psi. Probably the same reason it does physical damage in EP core. Any other feedback on the idea? I haven't had a chance to playtest it yet. I'm toying with the idea of only allowing players to mark stress before they roll dice. This makes Psi slightly more unpredictable. I'm worried that combing this with fate points would lead to crazy high rolls. I probably need to cap it at +2 or something. Maybe also slow down the rate that stress clears?
