Safety Wall...

[GM-Ayu]

decision varies depending on who you party with, or depending on guild that you are part of. Because safety wall is also shared by sage and priest, it makes it a unique situation where you may want to give up safety wall to do what is unique to only your class. However, safety wall does come in many usages, while spells like Lord of Vermillion, Meteor Storm (not too mob that SG cannot handle but MS can, and in woe, you only MS if there's already sufficient SG coverage first) are not nearly as flexible.

Personally, if you have firewall, you do not get safety wall. However, Firewall makes pvm life *much* easier if you are soloing, while safety wall isn't nearly as good in solo situations even though both of them are to protect yourself so monster cannot interfere your cast. Safety wall lets you "do something" to support teammates though even against an enemy that's spell immune or very high mdef, while fire wall being used to safe teammate is very rare. Safety Wall can assist in mvping, while clever usage of firewall can kill mvp (refer to the super popular "firewall kills RSX" youtube video). Firewall is far more useless in woe than safety wall, but firewall got amazing things to really help you mob monsters too.
