Hi everyone, I've been modifying Oblivion and one thing I'm trying to remove is the skill perk that makes your block skill remove all damage when you get to 50, is this even possible?

See http://cs.elderscrolls.com/constwiki/index.php/FBlockMax and other http://cs.elderscrolls.com/constwiki/index.php/Block. You'll have to experiment a bit because the exact formula is unknown. Good luck!
