Impale also has repercussions on the effect of a [Relentless Earthsiege Diamond] or [Chaotic Skyflare Diamond]. When a special (yellow) critical strike occurs, the 3% bonus of the meta gem is applied first, taking into account the 200% critical strike damage. This results in the strike causing 206% damage. The damage of a non-critical strike is then subtracted from this in order to determine the crit bonus damage portion of the strike which is 106%. This portion of the damage is then multiplied by the 20% bonus from Impale, resulting in 127.2% crit bonus damage, summing to 227.2% normal damage on the impaled special critical strike.
