Beacon of Ruin
Shocks from your Hits always increase Damage taken by at least 15%
20% more Damage with Ignite 
Beacon of Ruin is a notable Ascendancy passive skill for the Elementalist that grants more ignite damage, increased effect to non-damaging ailments, and grants chill and shock a minimum slow and increased damage taken effect percentage, respectively.
Mechanics and Interactions
Beacon of Ruin overrides the minimum threshold of 1% effect that normally applies to chill and shock. In other words, 1 point of cold damage from any hit will apply chill, and 1 point of lightning damage from a critical strike will apply shock. This also applies to damage types that are enabled by unique items, where 1 point of physical damage will apply chill when Soul Taker is equipped.
The Shocks from your Hits always increases Damage taken by at least 15% mod will be increased by X% increased Effect of Shock, up to a cap of 50% increased damage taken. For example, with 20% increased Effect of non-Damaging Ailments on Enemies, the minimum shock would then be 18% increased damage taken. An increased shock effect value of 334% is needed to reach the shock cap of 50% increased damage taken. This also applies to the mod Chills from your Hits always Slow by at least 10%, increased to the maximum of 30% slow at 200% increased chill effect.
