The Recon class says “Mud Cover Duration” as a bonus attribute of the class. But it doesn’t actually increase the duration of how long mud stays on you.
What it does is decrease the time it takes to put mud on you from 5 seconds to 4 seconds. But it still only remains on you for 1 minute and 40 seconds (which is the same as other classes).
So you could either change it to say “mud cover interaction” (so people know what you mean), or change the effect to increase the duration of the mud.
