Woodcrown the Ancient
"vile trespassers, you will pay for this intrusion with your lives"
Woodcrown is a Otherworld boss that drops Crests of the Hawk needed for Frozen Helm. This boss has a massive attack when the boss's health gets about half way that usually kills all those who are auto attacking it. In order to advoid this KO attack, stop auto attacking when you see the boss casting it when the hp gets half way.
