HelpHFS HELP DK/PALI DURRATATION~!

I can't seem to find out how Nico made the paladin and Darkknight last a whole day. I searched in the 763 and 564 hfs but can't find it only the boosting effects are found there.

lol, i'll give you a hint it's not in those HFS, and its pretty useless since current HFS mods are pretty much 1HK, just trans for exp.
