appearantly, they are. However, for me, it's a pain keepign an eye out for lightning shield at all times, since you have to recast it like every 5 seconds.
now, I've seen about the glyph of lightning shield.
"you're lightning shield cannot drop below 3 charges from dealing damage to attackers."
my question: what does this glyph do exactly? I don't remember consuming charges when attacking.
thanks in advance.
