Bonechill Support is a support gem that grants the supported skill more cold damage and increased chill effect. Enemies take also increased cold damage from all sources based on the magnitude of the chill effect applied by the skill.
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, VortexVortexSpell, AoE, Cold, Duration, Nova Level: (1-20) Cost: (13-25) Mana Cast Time: 0.75 sec Critical Strike Chance: 6.00% Effectiveness of Added Damage: 270% AoE Radius: 2Requires Level 28An icy blast explodes around the caster, dealing cold damage to enemies, and leaving behind a whirling vortex which deals cold damage over time and chills enemies caught in it.Deals (49-779) to (73-1169) Cold Damage Base duration is 3.00 seconds Deals (116-2316.1) Base Cold Damage per second Modifiers to Spell Damage apply to this Skill's Damage Over Time effect Base radius is 2 metres Base secondary radius is 2 metres

Chill, and therefore the effect of Bonechill, is capped at 30%. A chill that reduces Action Speed by 14% will cause the enemy to take 14% increased Cold Damage.[2] Since freeze is considered a separate ailment, it will not impart any additional damage bonus.[3]
