Given that my new spell works fine if I switch the effect for knock, can I assume that lockdown is just not programmed to work on the player? (... my mod is not starting out so great, no.)
Sleep also. Sort of. If you use the Psionics sleep spell (narcomatic whatzitosis) on an Evil Chest monster and it has Magic Reflect...you get stunned for 9+ turns. (don't know how long it lasts because my character only survived 9 turns of getting punching in the face while asleep). Players apparently don't have the "wake up when hit" code that monsters have.
