Death knight talent trees are complemented by Presences -- self-only buffs that work much like hunters aspects. Selecting the matching Presence for each tree augments the class abilities for that school of magic.
- Blood Presence - increases damage output by a percentage and restores a percentage of damage dealt as health.
- Frost Presence - increases threat and lowers damage taken by a percentage.
- Unholy Presence - increases attack speed and reduces the global cooldown on death knight abilities.
