These include Misdirection Hex, which can cause the Revenant to miss its blows, and Curse of Mortality, which will negate its regeneration ability.
Another type is spells that while not immobilizing the Revenant, will reduce its ability to fight.
Spirit Prison, Cone of Cold, and Petrify qualify. One type of talent is spells that can hold the Revenant still. To defeat a Revenant, it helps to have a healthy mix of 2 or 3 types of talents. It can also use Telekinesis to pull opponents within melee range. It can swing its weapon in an arc, causing lots of damage to multiple nearby enemies.
A Revenant is an incredibly powerful opponent in its own right.
There will also be a few Skeleton archers north towards the entry to the castle itself.
