Fire wall fery useful for STR bowers.
Firewall -> Strong bow -> Anti-devil = dead INT.

Not really. Takes 1 or 2 shouts to put down the fire wall if it is maxed. A pure INT spear will just use the last fan storm book and outlast the firewall.
Idk about s/s though, as I am not one of those.
But yes, firewall is a must because it gives you the first shot. I beat a zerked sosun INT spear by using it.
