Khroma, Warden of the Vents is vastly overtuned

Khroma unique mob has:
- A temporal shield that extends to a 32 radius (64 diameter). They can only be damaged, from inside the bubble. This is almost screen-wide immunity.
- The mob also has a +30 strike range bonus to regular attacks and a +40 range bonus to sweep
- The +30 range causes a 60 wide aoe sweep (stronger and faster with ally and area buffs).
- The mob also has a %100 pierce, extra projectiles, 50% phys to chaos mortar attack..
- The mob cannot be slowed below 70% of action speed

This is absolutely unreasonable. The mob cannot be damaged without being inside the bubble and cannot be damaged from inside the bubble without dying to their attacks (unless you are playing a few very specific phy/chaos tanking builds or have trivialized the content by running a broken damage build like explode totems). Please review and adjust this unless you really feel this is an example of "high quality design" for a non-boss within a map.

Thanks.

I'm getting 100% repro on this bug.

What's worse.. if you do manage to kill it there are no drops! Such a waste of time

I came here since I just faced that guy and died 5 times, could not kill...
I have like 200K EHP + 20M Minion DPS, but no way to kill that guy...
