I don't think RDD gives knockdown immunity. Immune to fire, paralysis and sleep according to the neverwinter grimoire. Only way to get knockdown resistance is to have a high dicipline as far as I know. I'm sure you could find an item that gives it though.
I probably confused it with something out of an item, yeah.
Sorc lvl is useless now. I took it for the lockpicking pixie but bard with high UMD would've been far better. (and more cheesy)
I took bard rather than sorcerer because, well, just more HD to go with overall.
Incidentally: yay Overwhelming Criticals and absurdly, absurdly high STR!
