Bonechill Support is a support gem that provides damage bonuses, mostly for cold damage over time, against enemies that are standing on chilled ground created by the supported skill, or have been chilled by the supported skill.
Skill functions and interactions
While seemingly redundant, the four lines regarding the damage effect are distinct from one another:
- Chills caused by a hit skill, with a fixed value for Damage Over Time taken
- Chills caused by an area skill, with a fixed value for Damage Over Time taken
- Chills caused by a hit skill, with a scaled effect for hit damage taken
- Chills caused by an area skill, with a scaled effect for hit damage taken
In all four situations the chill must be caused by a skill, regardless of whether the cold damage originates from a piece of gear, or the skill gem itself. If the enemy is affected by multiple sources of chill (for example, Vortex both hits and creates a chilling area) then only the strongest chill will receive the damage bonus.[1] Notably, sources of chill such as Aquamarine Flasks will not provide a damage bonus, since a flask is not a skill gem, nor are flasks linked to support gems.
Chill, and therefore the effect of Bonechill, is capped at 30%. Since freeze is considered a separate debuff, it will not impart any additional damage bonus.[2]
