Int Spear its awesome build i really love it
but still have short time to kill [only 2min - snowtime to kill when snow end they die even while snow they can die]prefer cold-fire on light-cold.
my favorite set for Int chars is Protector.
good phy defence and also -10% mp using. can use higher snow.
with armor maybe you have huge phy defence, but its mp waster! low snow to use.
fly dragon books are importent! i love make the combination with
sse+sss [till stun] than nuke->fly->ghost.
