it's nice, but the reason why noone uses it is because it doesn't have def bonus, just vit.
at low levels, defense is a lot more important for tanks.
i think this is the best combo for a pld tank
start out with steamed/boiled crayfish > then move to boiled steamed crab till def hits about 200, then move to shallops tropicale for galkas or seafood stew for other races, if you have gil to throw around grab some tavnazian tacos.
that's probably your best bet nowadays.
foods like that are good, but there is better stuff out there for tanking that gives vit +4 as well as def bonus.
makes me wonder why they even put these food items in there if there is something better out there.
