Hey! I'm glad you like it :)
Restrained currently should reduce your max to hit chance by 10, and increase enemy max attack chances by 10 (the minimum attack chance is half the max, so if a goblin can grab a naked heroine with a 40% hit chance max normally, if she's restrained then the max chance goes to 50% and the minimum to 25%, so every grab attack from that monster will be between those chances.
Ha! And I was going to write about being ordered to kneel and how that works, but I checked the code and ... you're right. It does currently does nothing, you can safely be ordered to kneel and just...stay there kneeling, it doesn't affect your chances in the fight. My bad!
