Is Max Block worth it for a FO MF sorc?

[Chesspiece_face]

another point: it depends on where you want to MF. If you plan to do a lot of Meph runs the need for high block goes up a lot. not just for the ice orb like griselda said, but the undead fetish's on the way down there will eat you apart in a second (no matter how high your life is.) having high block can allow you to, fairly easily, do meph runs where without it you would most likely die on any map where you don't find the stairs in a few seconds.

You shouldn't be in one place on that map for more than a second or two, and you wont be running or walking in most circumstances so you just need to live through those teleports that bring you into a pack of fetish's.

edit: just noticed that caaroid kinda mentioned this.
