I have been having a lot of trouble with this dungeon, first reason being by the last battle i have had about 4 companions faint, i'm at 400 health and i cant beat it because the ophidians critical rates are insane it seems like every hit they have a critical attack and it annoys me sooo much i have re-tryed this dungeon for nearly 2 days now and i cant beat it because of this please if someone can help me,

P.S this is a Valencia 2 quest where you go to quarry cave to get marble for a unicorn statue so you can bring it to some guy and maybe he will let you get someone out of jail )trying not to spoin it for people who havent gotten this far
