@Kabam Zibiit as you have told me to put it in the bugs and known issues category here it is
1.corvus interaction with physical resistance 
When he applies an armor break his damage against champions with physical resistance or nodes with physical resistance is greatly reduced whether this is an intended reaction between armor break and physical resistance corvus has true damage so it should not matter anyway
2. Corvus immunity does not always work ( more prominently in map 7) he will sometimes take damage against freezerburn bleed and shock nodes and coldsnap from iceman signature ability 
here is a link to another post with evidence 
https://forums.playcontestofchampions.com/en/discussion/144592/corvus-taking-coldsnap-damage#latest3. Corvus sp1 attack bonus is being considered a buff 
when corvus applies an armor break and uses an sp1 he gets 100% of his base attack as a bonus but it does not appear as a buff or is described as a buff yet it still activates buffet 
Please acknowledge all of the bugs above
