Higher difficulty has better drop chances.

This.

But it can still take forever.

 So disheartening.

For the rares, the utube guys say like .5 to 1% range, but it is like all of Plarium odds, they do not apply to any one account or any one activity.  Like in a casino they are group average rates over some longer period than the period in which you are playing. Unlike a casino there is no governing entity that is monitoring compliance with posted odds.

So just grin and bear it, some drops will take longer than others for no apparent reason.  Once I was trying to get Heiress from Palace of Aravia, I got 5 or 6 of Avenger b4 I got Heiress.

So I would go for the lowest energy expense unless you need the XP also.

Becuase that is how variability is. 

And NO, for anyone looking in the future, do not go for the lowest energy expense. As difficulty increases, so do your drop rates. Run the highest one you can when looking for a specific champs.

You allways need XP. 

The point when you don't need XP anymore is: you are in Platinum arena in classic and tag, you can speedfarm all dungeons lvl 25, you beat all faction crypts, you 1-key UNM CB, beat the highest Hydra and every DT rotation while your champion roster and vault is filled to maximum with lvl 60 champs. Congratulations, you don't need XP anymore!

Thinking that "you don't need XP" is the most ineffective way to play the game. Farm the campaign rares in brutal with one farmer and three food champs or don't farm them.

This reminds me of trying to farm for warmaiden. I can't remember the exact amount of energy I used but it was for sure over 800 trying to get her maybe just tipping the 1k mark.

like with anything Plarium, you will never get a specific definitive answer. You get what you get, that is the only rule you can count on.  Jump on and off, sometimes you may catch a streak, or not.   Everyone will have a different result. Plarium is run by a casino company, let that be your guide. The possibility of winning always keeps players in the game.

If you want to see the extensive depth of this quandry, click on the search button for this forum and type "drop rates". There is a file for drop rates of all kinds, for some reason they do not include the drops for campaign champs, I dare not post it I could be accused of spamming.  But if you do that search you will see the file, under title name Bobo.

I just don't understand your way of reasoning through things. Do you understand what probability means? I'd suggest you go back and pick up a university Statistics textbook.

No, there is no concept of "group average". Each roll is independent of the other. If there is a 1% chance of something occurring, and it hasn't happened 99 times in a row, that 100th time is NOT any more likely to have the event occur than the 1st time. If you get the event to occur for you, it has *zero* influence on whether it will happen for me.

If you wanted to validate this for yourself, you have all the tools you need. Simply take your autobattles, however many you have, and fire away. At the end of the autobattle, you'll have a more than sufficient sample size to calculate it for yourself.

If you are willing, try 100 runs at 3 diff difficulties and let us know the result.  The proof is in the pudding.  People can say anything and post "odds" but it is what happens to YOU that matters.

I don't farm campaign anymore, so no, I will not run this just to validate your own delusions, sorry. But once again, no, what happens to you does NOT matter. That's just you deluding yourself again.

There are Plarium employees monitoring every player that is online, and one of them dislikes for unknown reason horsemen. So everytime horsemen would get a good loot, that Plarium employee pushs the delete button and horsemen gets only trash reward. Odds have no influence on that.

If I'm not mistaken, you can farm more on high difficulty. But who needs that when you can farm real money playing online games. You can try golden-pokies.casinologin.mobi  and see for yourself, winning at least a small amount to start with. This online casino can be fully trusted, because it has a gaming license and impeccable reputation among its players.
