I'm pretty satisfied with my treatment of psychic sorcery aka psionics in Dying Sun. I'm especially pleased with making Psychic Combat mirror physical combat, as that keeps a lot of the cool, tactical nature of Ye Auld Game's system, while making it cleaner too. But one thing bugs me: it's asymmetrical. What I mean is that with 5 Modes of each type (Attack and Defense) and three relevant Abilities (INT, WIS, and CHA), you can't match things up neatly.
See, only 1 Attack Mode damages CHA, as opposed to 2 each for INT and WIS. Because of that, only 1 Defense Mode is good at protecting CHA. Is this a dumb concern? Probably. But you know how I love symmetry in design. If I were to follow that impulse, I would have to change the whole basis of the thing, by adding another Mode in each category.
Which broaches the larger question: is it worthwhile to keep those names from YEG? Crikey, is it even legal to use those names? I never even thought about that. Hmn.
