Yesterday I was playing index w/ Rhino and had 55% efficiency on my build. I had 2 stack financial stress and my energy would almost completely drain away in a matter of seconds. To cast one iron skin I would have to race to gather three energy orbs on top of energizing dash being on. Next game I switched back to 100% efficiency and was able to do the same iron skin cast with energizing dash alone (same financial stress). FYI all of this took place in second round on high risk.

This leads to my question, does energy drain from financial stress scale off your frames efficiency?? I feel like I am wrong about this, but I've never seen my energy drain that fast on Index.
