The fade starts when below 12secs but 0.2 is added to stop the opacity from dropping below 20%, this means there is no effect above 8secs.
I will double change the starting point and half the minimum opacity, so now it starts below 24secs 18 seconds but with 0.1 added.
It is nothing more than
local function HealBot_Icon_AlphaValue(secLeft, curFrame)
if secLeft>=0 and secLeft<18 and Healbot_Config_Skins.Icons[Current_Skin][curFrame]["FADE"] then
elseif secLeft>=0 then
