I know this is a silly question but - you are sure that BEK is your lead on CB, right? Aura only works if the champ is lead.

Also, the vast majority of BEK's damage is from poisons. You mentioned changing the hat resulted in some stats changing, but the one thing you didn't mention is whether his accuracy dropped significantly. That has a direct impact on how much damage he does.

But more broadly speaking, I think you have bigger problems to address. 42K HP is acceptable, but 2300 DEF is really, really low. You want closer to 3000 DEF, and you definitely want to make sure you always have DEF up buffs active.

Lastly, it goes without saying that you should make sure you made *no* other changes. Often people forget about things like the Faction Guardians speed buff on the last tier, or changing masteries. Remember that even a single point of speed changing on ANY of your CB champs could completely change your outcome.

I mentioned all the changes that occurred, his play order didn't change, nor did any other stat. I have both hats and can directly compare the changes next to each other.

no change in faction guardians either, nor anything else, only thing that changed with the hat

so far only my stagknight and zelotah have defence as high as 2800, and 2800 pretty much tanks the last scarab on normal doom tower difficulty but am unable to defeat him due to a lack of damage as those two are the only ones that don't drop... my account is only four month's old, so its only a matter of time until I have better gear in order

That said, the discussion of what I lack is completely off topic.

The only thing I know what to do is wait for nm cb to reset, and then run it with the cb at full health with the new hat, and then change hats and run it again. If the first run is substantially lower than the second, then I have to keep the original hat which is 11% higher crit chance.

Well, I guess the first thing I should do is simply make sure Bad El is the leader, cause if the aura doesn't activite unless he is, then clearly Bad El would have 11% lower crit chance.

So you want to test if Bad El's Aura is working from the overall damage he does at CB? That doesn't make any sense! Normal hit damage numbers are shown in red, critical hit damage numbers are shown in yellow. Just watch two minutes of the fight and you will know if he allways does a crit.

Reason that probably lowered his damage: in order to use his aura you moved him to leader position. If there is no weak affinity champ as main target (and you never have weak affinity to void CB), the CB tends to attack the teamleader with his stun hit.

Hi, it would be much easier to judge what is going on, if you can provide the video of the fight and the champions' stats.
