It says you get 10 fervor and then on the effects its says add 12 fervor to spells and combat arts. Now when I equip the rune, I only see fervor goes up by +10 to on my character sheet. Why is it not going up by +22 please? bugged?
the blue effect shows on your stats because it effects everything while the +12 only affects spells, so it's directly added to them. for exemple it doesn't add on procs or whatever buff you could have.
