Demonology is the second of the Warlock's three talent trees. It is centered around improving the Warlock's minions, Stones, Stats and survivability as well as the warlock's two armor spells. The key talents include Summon Felguard, Soul Link, Demonic Knowledge and Master Demonologist. It is often taken at mid levels (40+) for Demonic Knowledge which provides a substantial increase in damage before much gear with +spelldmg is available.
