Skitterbots not affected by Champion of the Cause or Mana Mastery reservation efficiency effects

Found this bug when using a Righteous Fire tank build with Skitterbots supported by Infernal Legion, using some auras to fully tank the damage of Righteous Fire, but Skitterbots doesn't receive the Reservation Efficency (reduction) effects.

Both passives mention "Mana Reservation Efficiency of Skills" or "Reservation Efficiency of Skills".

This means that Skitterbots should be affected by them.
Neither passive states it only affects auras, but ALL skills that reserve mana, yet the cost of Skitterbots remains at the base 35% mana reservation, so this definitely is a bug as it isn't behaving as the passive texts state.



This image shows that the cost of the skill remained at 35% after all calculations were done at the key bar and it was indeed reserving 35% of my mana, but I had both passives that should reduce its cost.

It's reservation isn't being affected by reservation efficiency.

You mention that your skitterbots is supported by infernal legion which has a 120% mana multiplier, this also increases the reservation of skitterbots.
Can you compare the reservation with another aura that reserves 35% or remove the support gem linked to skitterbots and see if your reservation then goes below 35%?

Oh! Thank you. Yeah, that explains it. Somehow the math made it go right back to the original 35% and I didn't notice. It was being reduced but the increase was just exactly enough that returned it to the original cost.
