Follow up to slot 4, Afterwards, depending on how the match is going and what kind of enemies there are, you could either grab Physical Armour and Health, Energy Armour (Tuned Barrier) and Health, Both Physical and Energy Armour or Both Health.
When using Reversal of Fortune (ULT), be sure to use the Honor the Pure Active as soon as you land if you are in a team fight with several other allies. If not, use so accordingly.
Be sure to focus on your RMB and E abilities first, then grab your Q. Afterwards, focus on leveling up RMB and E as much as you can and grab R (ULT) as soon as it pop's up each time.
Hope this helps some of you :)
