Safety Wall...

[F.x]

for a Wiz to sacrifice something for Safety Wall, is it wroth it?

in general HOW useful is safety wall, i know that when u mob at let say Rachel Sanc it can be handy.

for a Wiz to get safety other skills may need to be lower so there are enough points for SW and its requirements.

is safety wall better to have for a Wiz than for example maxed lvl FW, or meteor storm. (those are the ones i'd sacrifice for SW)

i want to see your opinion so i can make a better decision on my Wiz
