Infernal Shade is invisible most of the time

i play a flickering shadows sacrifice infernal shade necromancer. whenever one of my minions is sacrificed it buffs my infernal shade but sets it remaining duration to 2 seconds which means i have to micro manage my minions and make sure that i am constantly casting dread shade about every 1-1.5 seconds to make sure that i keep the infernal shade alive, or else i have to start the whole process over again from the beginning. it is really fun and i love playing necromancers and this is still one of the most fun necromancers ive played even despite the major difficulties with the bugs, but it is really frustrating that i cant just play it to the fullest enjoyment because its invisible the whole time
