# Kongming's Stratagem ## Mechanics Kongming's Stratagem triggers level 20 [[Fog of War]], which is affected by socketed support gems regardless of whether they are linked. However, since Fog of War is not granted by a skill gem, it cannot be supported by [[Empower Support]], [[Enhance Support]] or [[Enlighten Support]]. [[Fog of War]] creates a smoke cloud in an area when triggered that lasts for a base duration of 3 seconds. It can be compared to a [[Stibnite Flask]]. [[Fog of War]] can be supported by area and duration support gems such as [[Increased Area of Effect Support]] and [[Increased Duration Support]], while its trigger cooldown can be modified by items like [[The Flow Untethered]].
