Why not advance to 20? It definitely increases your chance of getting superiors.

Yes, it's a huge difference.  I can run 25 times and pull more superior potions than he did with all of his energy.  It's the only way to go, IMO.

If I could do that I would have done it...I can run only lvl 15

Also I know that lvl 20 gives more superiors...But lvl 15 should also give decent amount of them. Just 3 in a whole day is so ridiculous...Must have spent around 600+ energy

Mods..Pls check this issue

I can understand that its rng....But rng to this extent is ridiculous

I am sure I had better drop rates before. Thats why I was so frustrated today and writing this post.

Your total odds of getting a Superior potion increase from 12% to 35% (L15 to L20).  That's a little better but at least in L20 you are done with the Lesser potions. Still have brews and shards to frustrate you.

Plarium RNG math does not work like regular math, anything that has odds posted is usually baloney, IMO.

You can use RAID: Shadow Legends CB/Dungeon Stats and Drop Rates by Bobo - Imgur  to see the drop rates. Level 15 has a 12% chance to drop at least one superior, so going through a full day's worth of energy for a total of let's say 40 runs, your expected value is roughly 4 superior potions. You got three, which is ... pretty close to the expected value. Conversely, level 20 has 35% chance to drop at least one superior, which is roughly three times that of level 15.

The drop chance at lvl 20 is really ok. Until the update a few weeks ago stages higher than 15 didn't even exist and we all had to take the really bad drop chance of lvl 15.

Maybe we could help you to find a team that can beat stage 20 if you share your roster. 

For example: I use Peydma and Teela Goremane to steal the shield buff from the boss. Teela was my first legendary and she was appointed as the worst legendary in the game. But I think her value increased a lot when the keeps got lvl 20 stages, she is great at magic and spirit keep. Maybe you have some good buff stealing or removing champs in your roster? For magic keep Ogryn Jailer is great as well.

Yes, why not just do the harder thing >.<

Seriously it wasn't obvious why? 

If you're struggling with the higher potion keeps - just don't bother farming them until you can do them. They're not challenging at all to overcome. Especially for someone who has seemingly been playing the game for over two years now.

i've spent over 2500+ energy between 13 -15 and attained:

- 1 superior potion

- 2 brews

- 0 shards

- hundreds of lesser potions

3 weeks still stuck on this progress mission

Didn't even need the potions, as I already had 25 Superior from farming Lvl 10 only on month 3 of play

The math is not mathing, 

the "arbiter progress mission" may be causing some issue because the other potion keeps drops while not great are consistant with the charts for me

Sounds fishy. Did you really spend that much energy with 100% win rate? because you should have something like 1000 lesser potions, and something like 100 greater potions.

Check that you're actually winning all your runs. It's easy to waste hundreds of energy on unsuccessful multi-battles.

it happens sadly, i told my self yesterday i needed an accuracy banner for my skrank, im still here about 80 spider runs later waiting for one :D
