I did Seph EX and failed it with 3secs and 2% HP, literally it just stopped with time on the clock. I'd say that is pretty good but they do fail to give accurate representation on it as some skills become useless or unusable. While I know some I can't really depends on like the proc for parrying an attack its still damage or the missed MP from Blood Price to allow more Dark Art uses. Otherwise I welcome them and enjoy it, havn't really tried much else.
